Fuel-pump problems can cause long cranking, a no-start, stalling or weak acceleration in a 2005 Chevrolet Equinox with the 3.4L V6. P0171 means the fuel-trim system is lean on bank 1; P0230 concerns the fuel-pump relay control circuit. Both are diagnostic clues, and neither proves that the pump motor has failed. This guide covers the right primary fuel pump on the front-wheel-drive model, after the cause has been established. See GM’s P0171 diagnostic explanation and P0230 relay-circuit procedure.
The exact vehicle and repair covered here
The worked configuration is a 2005 Chevrolet Equinox FWD, 3.4L gasoline V6, VIN engine code F. The factory route removes the fuel tank after the exhaust assembly and EVAP canister are removed. Inside the tank, the primary pump connects to the secondary sender through a formed suction tube and electrical lead, so both tank openings are serviced and both need new seals. The serviceable secondary assembly is reused.
These are planning estimates for the mechanical job after diagnosis, with the correct lifting, fuel-handling and lock-ring equipment already available. Corroded exhaust hardware, damaged fuel lines or tank contamination add work. The broader product applications below do not make the FWD procedure universal; GM gives AWD a separate access sequence.
Featured replacement module
The submitted product is A-Premium APFP0152C, ASIN B07G9CDKVY, sold as one electric gasoline fuel-pump module. The corresponding manufacturer catalog number is APFP0152. Its specification lists a 12-volt pump, fuel-level sender, float, pressure sensor and gasket, with a strainer inlet. On this vehicle the sensor measures EVAP fuel-tank pressure; delivery pressure at the engine still requires the mechanical gauge. The external vehicle wiring harness is not included.
The selected package photographs show an attached float and attached fuel/transfer lines, a separate black lock ring and rubber sealing parts. The top electrical connections are a six-pin module connector plus a separate three-pin sensor connector. Compare the delivered connector keying, line routing, float and tank flange with the original equipment before beginning.
Have both correct new tank seals in hand. Package pictures differ in the number of rubber seals displayed, and color does not establish their size or profile. The large primary opening and smaller secondary opening use different seals. The tool-and-parts table identifies the separate OEM references to use if the supplied pieces do not positively match. The metal lock ring and rubber tank seal serve different purposes.

Complete product compatibility and restrictions
The manufacturer’s five application rows support the following gasoline vehicles. Installation side and the 2006 production cutoff are part of the fitment, not optional details.
| Vehicle | Model years | Engine | Installation side and restrictions |
|---|---|---|---|
| Chevrolet Equinox | 2005 | V6 3.4L gasoline | Right; MFI Fuel SYS |
| Chevrolet Equinox | 2006 | V6 3.4L gasoline | Right; 1st Design; To Chassis# 66035231 |
| Pontiac Torrent | 2006 | V6 3.4L gasoline | Right; gasoline |
| Saturn Vue | 2004–2006 | L4 2.2L gasoline | Left; gasoline |
| Saturn Vue | 2004–2006 | V6 3.5L gasoline | Left; gasoline |
The 2006 Equinox entry is first design through chassis number 66035231. Confirm the full VIN and original module with the parts supplier; a matching model year alone is insufficient. The Vue uses the featured part on the left, while the Equinox and Torrent use it on the right. The catalog does not provide a transmission or drivetrain qualifier in these rows, so use the exact vehicle’s procedure for those differences.
Confirm the fault before lowering the tank
Check the actual fuel quantity and visible external plumbing first. A weak pump can lose delivery under load, but a line restriction, an electrical supply fault or the tank’s internal transfer system can produce similar symptoms. GM describes a returnless system with primary-to-secondary transfer plumbing; the separate tank-pressure sensor monitors the EVAP system.
Interpret the stored fault codes
- P0171: low fuel delivery can make the engine run lean, particularly under demand. Intake/vacuum leaks, exhaust leaks ahead of the oxygen sensor, injector problems and contaminated fuel can produce similar evidence. The complete GM code-specific repair path includes a scan-tool Fuel Trim Reset; a basic code reader is not a substitute for that function.
- P0230: investigate the relay-control circuit, relay connections and associated power/ground faults. It does not mean that the in-tank pump has automatically failed, and GM does not specify a malfunction-indicator lamp request for this fault alone.
- Incorrect fuel level: this tank has primary and secondary level-sender connections. A disconnected transfer-side electrical lead or disturbed float can leave the gauge inaccurate even when the engine runs normally.
Record stored codes and the available freeze-frame data before clearing anything. A reader can preserve those clues; relay commands, circuit testing and code-specific resets require the appropriate diagnostic equipment and procedure.
Measure delivery pressure at the rail
Use the correct threaded fuel-rail connection and a bleed-capable gauge. Obtain the current exact service pressure range for this vehicle before judging the reading. GM’s test uses ignition ON, engine OFF and a capable scan tool commanding the pump. The listed genuine Tech 2 setup requires its CANdi interface and the correct GM vehicle software. Clean the connection, attach the gauge under a protective towel, place its bleed hose in approved gasoline recovery, bleed gauge air under the prescribed pump command, close the bleed valve and inspect the sealed setup for leaks. Record the pressure against the confirmed criteria.
A rapid loss of retained pressure also needs isolation diagnosis: the pump check valve/regulator, injectors, plumbing and connections are possible causes. Use GM’s gauge installation and removal method, fuel-system diagnosis and electrical diagnosis. A generic code reader does not provide the factory Fuel Pump output-control command.
Fuel, lifting and tool precautions
Work only with a cool exhaust, ventilation and all ignition sources controlled. Use splash goggles, correctly selected gasoline-resistant gloves, a ready Class B extinguisher and approved fuel-recovery and wet-waste containers. Collect line-opening fuel in the approved broad receiving assembly. Reserve the shallow tray for small drips from removed modules; recovered gasoline belongs in approved closed recovery/storage equipment.
Arrange the complete lift and tank-handling systems before disassembly. This walkthrough uses a full-height frame-contact hoist, its required vehicle retention/opposite-end support and a secured tank handler. Match their ratings, operating heights, attachment points and actual load. Engage the hoist locks before working beneath the vehicle.
The tank must contain no more than 11.4 L (3 U.S. gallons). A reliable below-quarter indication is GM’s service proxy. A faulty sender or failed transfer system can make that indication unreliable. The special filler siphon reaches the primary compartment; do not assume it empties both sides.
Complete both manual lock-ring tool chains first. The primary uses J45722; the secondary uses J39765-A with a properly matched driver longer than 12 inches. Confirm the exact mating connection, adequate handle length and secure tank restraint. Do not improvise with impact tools or striking tools. Both correct new seals, a new exhaust gasket and three new exhaust nuts must be available.
Stop for fuel leakage, damaged tank seats or retainers, trapped siphon equipment, unsafe support, or a connector that will not engage correctly. Complete the pressure/circuit diagnosis and establish the correct pressure-test criteria before committing to the replacement.
Tools, parts and supplies
This inventory covers the stated FWD tank-removal route, including pressure testing, fuel recovery, exhaust removal, both module openings and reassembly. The lift, jacks, stands, compressor and scan equipment must already be properly installed, maintained and ready for use. Select the complete required connections and restraints before disassembly; a tool name alone does not establish that its attachments fit.
Have both correct new tank seals, the correct new primary ring, one exhaust gasket and three new exhaust nuts ready. Reuse the serviceable secondary assembly with its own new seal. Existing suitable tools may be used; check actual load, reach, connector engagement and fastener heads before beginning.
| Tool or Supply | Exact Product | Product Link | Purpose and Selection Check |
|---|---|---|---|
| Grounded-wheel chocks | Fasmov solid rubber wheel chocks, two-pack | View exact product | Two rubber chocks for the grounded vehicle during preliminary diagnosis and lift positioning.

Select the exact vehicle before using Engine Output Controls/Fuel Pump; Fuel System/Fuel Trim Reset is for its specified diagnostic branch. Verify communication and the tool’s cable checks first. The older 71419 adapter and a basic code reader do not provide this required setup. |
| Controlled rail-pressure relief and measurement | Actron fuel-pressure tester kit — CP7818 | View exact manufacturer/OEM reference | The complete 0–100 psi CP7818 kit supplies a GM/Chrysler threaded service-port connection, relief control and 6-foot bleed hose. Fit the GM adapter finger-tight to the fuel-rail service connection; secure the bleed hose in the gasoline safety can and follow the original scan-command purge sequence. Relieve pressure to zero before disconnecting and drain the gauge into the can. Do not use a Ford adapter or an improvised open-container setup. |
| Light oil for the gauge adapter | 3-IN-ONE Multi-Purpose Oil, 8 fl oz drip bottle — 10038 | View exact manufacturer/OEM reference | Use only a small amount of this lightweight household oil on the tester adapter’s O-rings as the CP7818 instructions specify. Keep it off both tank-module seal grooves; those must remain dry. The bottle is not fuel-system cleaner. |
| Installed vehicle hoist | BendPak 10AP two-post vehicle lift — 10AP / 5175304 | View exact manufacturer/OEM reference | An installed, inspected 10,000 lb 10AP lift, rated 2,500 lb per arm, is the reference for this workshop procedure. Verify the actual loaded vehicle and each arm load, use the exact GM underbody lift-point diagram and the correct pad contact, engage all lift locks, and leave room for the tank handler and exhaust supports. The GM procedure also requires opposite-end supplementary support and an approved vehicle-to-hoist restraint; select those before lifting. |
| Opposite-end vehicle supplementary supports | OTC high-reach underhoist supplementary stand — UH20 — quantity 2 | View exact manufacturer/OEM reference | Use two UH20 stands at strong, stable OEM-approved structures at the front, opposite the rear tank/exhaust work. Set a lift height within their 56-1/4–85 inch range and keep both bases fully supported on the level floor. They supplement the locked vehicle hoist; use the proper saddle contact and do not try to lift the vehicle off its pads. |
| Required vehicle-to-hoist restraint | Hoist-manufacturer-approved restraint for the actual Equinox/lift arrangement | Required: match the approved hoist-restraint arrangement | Before removing the tank or exhaust, obtain the lift manufacturer’s approved restraint arrangement for this vehicle and installed lift, including its rated straps, attachment points and routing. Do not improvise with a cargo tie-down around a brake line, exhaust, suspension link or lift mechanism. Opposite-end stands do not replace this restraint. |
| Under-hoist tank-support jack | OTC manual high-lift transmission jack — TJH10 | View exact product | Use the inspected, assembled TJH10 with the separately listed 1758 handler and its specified mounting hardware. Its saddle starts 35 inches above the floor before the handler is added, so verify full entry, lowering and removal clearance under the raised vehicle. Account for the handler plus tank and permitted residual fuel within the jack rating. This jack never supports the vehicle. |
| Tank cradle, attachment and restraint | OTC fuel tank handler — 1758 | View exact manufacturer/OEM reference | Attach 1758 to the explicitly compatible TJH10 using the supplied plate/hardware, then adjust all four pads to sound areas of the actual saddle tank without crushing lines or fittings. Follow GM’s no-more-than 11.4 L/3 US gal fuel limit, keep the tank as level as possible, restrain it with the supplied strap as it clears the vehicle, and fully retract the jack before transport. “Up to 40 gallons” describes tank size, not permission to handle a full tank. |
| Grounded gasoline-recovery cart and temporary service storage | JohnDow PRO30 manual fuel caddy — FC-P30-UL, red gasoline configuration | View exact manufacturer/OEM reference | The red gasoline FC-P30-UL is a 30-gallon manual, reversible-pump service caddy with an 8-foot grounded hose, correct gasoline filter and grounding equipment. Check free capacity and the maker’s fill limits, then bond/ground and operate it as instructed. The required J45004-to-cart connection is a separate selection prerequisite below; the caddy’s ordinary hose must never be pushed through the Equinox filler check valve. |
| Factory fuel-drain insertion hose | GM/Kent-Moore fuel tank drain hose — J45004 | View exact manufacturer/OEM reference | For an inoperative pump, use J45004 through the flapper holder. It reaches the primary side only; never pass the tag/end fitting into the filler funnel. GM places the bottom reach about 10 inches from that end fitting/tag. Do not substitute ordinary hose or assume this empties the other saddle. The cart connection must be established before inserting the hose. |
| Factory filler-door holder | GM/Kent-Moore fuel flapper door holder — J42960-2 | View exact manufacturer/OEM reference | Hold the filler flapper with this exact OEM holder while guiding J45004. Follow the original insertion instructions and remove both tools after draining. The holder does not make an arbitrary siphon hose safe for the tank’s check valve. |
| Required drain-hose to recovery-cart interface | Gasoline-rated J45004 extension/coupling matched to the selected recovery cart | Required: confirm the complete compatible drain-hose connection | Obtain a documented compatible, gasoline-rated extension and coupling between J45004 and the recovery cart before draining. Confirm the exact interfaces at both ends, the sealing method, grounding continuity and the cart maker’s permitted connection. Use the specified matched fittings throughout the complete hose connection. |
| Required broad fuel-spill receiving assembly | Approved gasoline collection assembly with at least 300 mm/12-inch receiving opening | Required: match the approved 12-inch receiving assembly | Arrange an approved gasoline collection assembly with at least a 12-inch receiving opening for residual fuel when opening the lines. Confirm its fuel approval, attachment, closure and compatibility with the recovery system. The shallow module drip tray and the small funnel on a safety can do not satisfy this specified receiving arrangement. |
| Metric sockets, ratchet and extensions | TEKTON 3/8-inch drive 6-point socket and ratchet set — SKT15201 | View exact product | This 3/8-inch-drive six-point set covers 6–24 mm with its ratchet and extensions. Fit the actual undamaged hex heads for battery, canister, tank straps, filler clamp and exhaust hardware; the OEM thread sizes do not establish socket sizes. Use the included manual ratchet for removal, and the listed torque tools for final tightening. |
| Low-range square-drive torque wrench | LEXIVON 1/4-inch drive inch-pound torque wrench — LX-180 | View exact product | The 1.1–16.9 N·m range covers the 2 N·m battery-cover screws when a hex socket fits, 5 N·m filler clamp and 9 N·m canister nuts. Use the coaxial SHA04101 adapter with the listed 3/8-inch sockets. Match the real fastener head and use the correct scale. Its upper limit does not cover the 17 N·m battery terminal; use the medium-range wrench there. |
| Low-torque square-drive adapter | TEKTON 1/4-inch female to 3/8-inch male drive adapter — SHA04101 | View exact product | The SHA04101 accepts the low-range wrench’s 1/4-inch male square and presents a 3/8-inch male square for the socket set. Keep it coaxial and fully seated; it changes square size, not the chosen 2/5/9 N·m torque. It is not an offset crowfoot or a ring-tool adapter. |
| Battery, tank-strap and exhaust torque wrench | EPAuto 3/8-inch drive click torque wrench, 10–80 ft-lb | View exact product | This 3/8-inch-drive 10–80 ft-lb wrench spans about 13.6–108.5 N·m, covering 17 N·m at the negative battery terminal, 25 N·m at tank-strap bolts and 37 N·m at the three new exhaust flange nuts. Use a directly mating socket from the set, clean specified fasteners, and stop at the first click. It does not cover 2/5/9 N·m. |
| Conditional recessed-screw torque driver and bits | Capri Tools certified torque-limiting screwdriver set, 10–50 in-lb — CP21075 | View exact product | If the battery-cover screws use a recess rather than an external hex, fit the matching included Phillips, slotted, Torx or hex bit directly in this 1/4-inch-hex driver. Set 18 in-lb, the OEM companion value for 2 N·m, and stop at the first release. Its 10–50 in-lb range and 1 in-lb increments cover that value. Confirm the actual recess; do not force an approximate bit. |
| Manual holder for the recessed-screw bits | Wera Kraftform 816 R Rapidaptor bit-holding screwdriver — 05051462001 | View exact manufacturer/OEM reference | This 816 R holder accepts the torque-driver kit’s standard 1/4-inch hex bits for manual loosening and hand starting. Choose the exact head fit and keep removed cover fasteners organized. Use the calibrated torque driver for the final 18 in-lb cover setting. |
| Primary-module retaining-ring wrench | GM / Kent-Moore fuel-sender lock-ring wrench — J-45722; current GM catalog GM-45722 | View exact manufacturer/OEM reference | Use exact J45722 on the larger primary/right ring. Its documented 1/2-inch square input mates directly with the listed 24-inch bar. Fully seat the wrench, keep the supported tank restrained, and turn manually in the OEM direction. No impacts, hammer or screwdriver driving, and no invented final torque. |
| Primary-ring manual breaker bar | TEKTON 1/2-inch-drive 24-inch breaker bar — SBH00224 | View exact product | The 24-inch SBH00224 has a 1/2-inch square that directly fits J45722. Its length exceeds 12 inches and provides manual leverage while the tank is secured. Do not add a cheater pipe. Its known input fit for the primary tool does not establish a fit to J39765-A on the secondary opening. |
| Required secondary-module ring wrench and manual drive | GM/Kent-Moore J39765-A ring wrench with a positively matched long manual bar | Required: confirm the complete compatible manual drive | Have exact J39765-A and a demonstrably compatible manual driver longer than 12 inches available before opening the secondary module. Confirm its actual input and tool engagement; no impact drive, hammer or guessed reducer. The primary J45722’s 1/2-inch specification cannot be transferred to this different wrench. |
| New primary/right module seal | GM Genuine Parts fuel-sender seal — 39002198 | View exact manufacturer/OEM reference | Have one correct new primary seal ready. GM 39002198 replaces the original 22682111 identified for this opening. Use an included kit seal only if its exact application/profile is positively confirmed; color alone is insufficient. Discard the old seal, clean the groove and install dry with no oil, grease or sealant. |
| New secondary/left module seal | GM Genuine Parts fuel-tank sending-unit O-ring — 21008100 / ACDelco G42 | View exact manufacturer/OEM reference | Have one new 21008100 secondary seal available because this opening is disturbed while replacing the primary module. Verify the part/profile rather than seal color: current GM photos and older catalog colors differ. An included second ring is usable only after an exact application match. Remove the old seal and seat the correct new ring without twisting. |
| New primary retaining ring for this procedure | GM Genuine Parts primary/right fuel-tank lock ring — 10325852 / ACDelco TR26 | View exact manufacturer/OEM reference | This worked procedure uses a new, correctly matched primary ring. A supplied new ring may be used only after confirming the correct primary geometry and seating; otherwise obtain 10325852. This new-ring route avoids reusing an old ring without the OEM seven-point flatness inspection. Do not substitute the smaller secondary ring. |
| Secondary retaining ring if replacement is needed | GM Genuine Parts secondary fuel-sender lock ring — 25691383 / ACDelco TR7 | View exact manufacturer/OEM reference | Inspect the secondary ring and use a new 25691383 if the original is damaged, distorted, corroded at its seating features or cannot lock correctly. Match the secondary opening and J39765-A engagement; the primary kit ring is a different part. Keep this correct replacement available when corrosion is present. |
| Penetrant for external lock-ring tangs | WD-40 Specialist Penetrant with Smart Straw, 11 oz, one can — 30000 | View exact product | Before attempting either ring, apply a small controlled amount to the external ring tangs as GM directs, with the tank still closed and all ignition sources removed. Allow it to work and remove excess before opening. Keep the spray out of the tank and off module-seal grooves; this is not a gasket lubricant. |
| Metal-collar fuel-feed quick-connect release tool | Lisle air-conditioning and fuel-line disconnect tool set — 37000 | View exact product | Use the 3/8-inch separator in the 37000 set for the OEM metal-collar chassis fuel-feed joint, after relieving pressure and removing its external safety retainer as directed. Keep the tool square and pull the fitting apart by hand. Plastic EVAP connectors and the internal suction-port tab use their own hand-release method; do not force this tool into them. |
| Clean temporary fuel and vapor line caps | Lisle Master Line Stopper Set — 67000 | View exact manufacturer/OEM reference | Fit clean stoppers/caps to the actual depressurized open lines without damaging seals. The set spans 1/8–1/2-inch stoppers and 5/8–3/4-inch caps. They exclude dirt while the tank is lowered and both modules are serviced; remove and account for every cap before reconnecting. Never use these small pieces as tank-opening plugs. |
| Fresh engine oil for fuel quick-connect ends | Shell Rotella T4 Triple Protection 15W-40 diesel engine oil, 1 gallon | View exact product | Apply only a few drops of clean engine oil to the male fuel-pipe ends where GM’s quick-connect installation calls for it, then fully engage and pull-test the joints. A small clean portion from this exact engine-oil product is enough; it is not an engine-fill recommendation for the Equinox. Keep engine oil off both tank seal grooves and out of electrical connectors. |
| Soft exterior cleaning and conditional battery brush | TEKTON mini wire-brush set, nylon/brass/stainless steel — 7064 | View exact product | Use the nylon brush for loose dirt around closed fuel connections and the tank top. If the isolated battery cable flange has corrosion, use the suitable metal brush carefully before reconnecting, with no fuel vapors present. Keep metal bristles away from open fuel fittings and remove all debris; do not bridge a battery terminal to ground. |
| Regulated air source, matched hose and safety blowgun | CRAFTSMAN oil-free 6-gallon compressor with 13-piece accessory kit — CMEC6150K | View exact product | Use clean, moisture-free regulated air and the supplied safety-nozzle blowgun to remove dirt from still-closed quick-connect joints before release. Set only the gentle pressure needed and keep safety vents clear; never blow into an open tank or line. The compressor motor, switch, cord connection and all ignition sources must stay outside the fuel-vapor area. Verify that the 25-foot hose permits this layout before work. |
| New exhaust flange gasket | GM Genuine Parts exhaust muffler flange gasket — 22720424 | View exact manufacturer/OEM reference | Install one new 22720424 gasket at the three-stud flange opened to remove the rear exhaust assembly. Discard the old gasket and clean the mating faces without gouging them. This is the muffler-pipe flange gasket, not 24505057 at another exhaust joint. Do not add sealant or substitute a visually similar gasket. |
| Three new exhaust flange nuts | GM Genuine Parts all-metal prevailing-torque flange nut — 11517996 — quantity 3 | View exact manufacturer/OEM reference | Obtain three new 11517996 nuts; the factory procedure replaces the removed nuts. Hand-start on sound original studs, align the new gasket/flange and tighten each to 37 N·m using the medium-range wrench. Do not add anti-seize or guess a substitute locking nut; damaged studs require the correct repair before assembly. |
| Exhaust-assembly support stands | OTC underhoist auxiliary component stand — UH15 — quantity 2 | View exact manufacturer/OEM reference | Use two stable UH15 supports and an assistant to control the cool exhaust assembly at separated, sound pipe locations while releasing its flange and hangers. Match saddle contact and the 54.25–80.75-inch height range before removing fasteners. Keep the assembly balanced and transfer it clear with adequate help. UH15 supports components; it is not a vehicle stabilizer or a wheeled transport jack. |
| Exhaust rubber-hanger release pliers | Lisle exhaust removal pliers — 38350 | View exact manufacturer/OEM reference | With the exhaust fully supported, use these hand pliers to push each hanger rod out of its rubber isolator without pulling on the whole assembly. Confirm the jaws can seat on the actual rod and isolator. Keep fingers clear and stop if a hanger or rubber support is damaged; no powered impact, heat or cutting is part of this procedure. |
| Conditional sacrificial plastic routing strap and cutting tool | OEM-correct fuel-line retaining strap and safe hand cutter if cutting is necessary | Before cutting: obtain the correct routing strap and hand cutter | If the plastic routing strap must be cut to free the module lines, first obtain the correct replacement strap and a hand cutter that can reach it without nicking the tank, lines or harness. Restore original routing and retention. Do not cut the structural metal tank straps, leave lines unsecured, or substitute an unverified zip tie. |
| Chemical-splash eye protection | 3M chemical-splash goggles — 91252H1-DC-10 | View exact product | Wear the correctly fitted 91252H1-DC-10 chemical-splash goggles during relief, quick-connect work, tank handling and ring service. Inspect the lens, seal and strap; ordinary open safety glasses are not the listed splash protection. |
| Gasoline-compatible chemical hand protection | Ansell AlphaTec Solvex nitrile chemical gloves; choose a fitted size — 37-175 | View exact manufacturer/OEM reference | Use undamaged 37-175 nitrile chemical gauntlets in a fitted size for splash contact, following Ansell’s gasoline permeation and replacement guidance. A fitted pair is required; do not assume unlimited immersion protection. Replace contaminated or damaged gloves and use the handling assistance specified for the tank/exhaust. |
| Accessible Class B extinguisher | First Alert rechargeable home/workshop fire extinguisher — HOME2PRO | View exact product | Keep the HOME2PRO extinguisher, rated 2-A:10-B:C, inspected and accessible from the work-area exit. Check its gauge and pin before the fuel job. Do not place it beneath the vehicle or where a fuel spill blocks access. |
| Small-spill absorbent | New Pig Universal Light-Weight Absorbent Mat Roll, 15 inches × 50 feet — 25201 | View exact product | Use the 15-inch×50-foot gasoline-compatible universal absorbent roll for small drips and prompt cleanup. Keep absorbent away from ignition sources and move used material into the approved waste process. It is not a substitute for the gasoline recovery cart or large receiving assembly. |
| Temporary removed-module drip tray | FloTool galvanized metal drip tray, 25 × 36 inches — 11430 | View exact product | Use the 25 × 36-inch galvanized tray beneath the removed fuel module on a stable surface to catch its small drips; support the module body without loading the float arm or lines. Transfer liquid promptly to approved fuel containment. This shallow tray is not gasoline storage, a bulk drain pan or the specified 12-inch fuel-receiving assembly. |
| Residual-gasoline safety can | Eagle five-gallon Type I red gasoline safety can with funnel — UI50FS | View exact product | Use the five-gallon red Type I can for the secured gauge bleed hose and small measured residual quantities, keeping within its fill limit. Maintain the flame arrester and self-closing lid and follow the can instructions. A single five-gallon can cannot receive the full 17-gallon tank contents; use the separate recovery cart for bulk draining. |
| Fuel-wet wipe and absorbent waste can | Justrite foot-operated oily-waste can, 6 gallons — 09100 | View exact product | Put fuel-wet wipes and compatible small absorbent waste in this six-gallon self-closing oily-waste can and empty it through the shop’s approved disposal process. It is for solid waste, not liquid fuel storage; keep its lid closed and do not fill it with drained gasoline. |
| Lint-free wipes and attended external dirt shields | Texwipe AlphaWipe dry polyester cleanroom wipers, 9 × 9 inches — TX1009 | View exact manufacturer/OEM reference | Use fresh dry 9 × 9-inch low-lint polyester wipes around opened fuel joints and for clean parts. If either tank opening is briefly attended while exposed, a clean dry wipe may lie across it only as an external dirt shield; never stuff material inside or treat it as a vapor seal. Remove and account for every cover before installation and move fuel-wet wipes to the waste can. |
DIY and professional cost planning
The following U.S. dollar ranges are illustrative allowances, not current listing prices or shop quotes. They assume one diagnosed primary-pump replacement, a serviceable secondary assembly and ordinary removable hardware.
| Expense | Planning allowance | Scope |
|---|---|---|
| Replacement pump module | $140–260 | One correctly matched aftermarket primary assembly |
| Required seals, retention, exhaust hardware and supplies | $35–90 | Any separately needed primary/secondary seals, the correct new primary retaining ring, a new exhaust flange gasket and nuts, plus small consumables; avoid duplicate correct kit parts |
| DIY parts and supplies | $175–350 | The preceding allowances, with diagnosis and suitable equipment already available |
| Lifting, draining and special tools | Price separately | A complete vehicle/tank support arrangement, gasoline-handling equipment and both matching lock-ring tool systems |
| Professional labor example | $360–900 | An assumed 3–5 billed hours at an illustrative $120–180 per hour |
| Professional repair example | $585–1,350 | That labor plus an assumed $225–450 shop parts/supplies allowance; diagnosis, tax and additional damage excluded |
Ask whether the quote includes fuel-pressure diagnosis, both new module seals, the correct primary ring, new exhaust gasket and nuts, internal transfer connections and fuel/exhaust leak checks. If you must obtain all the lifting and gasoline-handling equipment for this single repair, compare that total with an equipped shop’s quote before buying tools.
Replacement sequence: 2005 Equinox 3.4L FWD
The steps below follow the original GM FWD tank-removal route. Keep the secondary assembly for reuse if serviceable. Work through the preparation and tool checks before opening either module; the hidden internal connections make removal order important.
1. Prepare the vehicle and replacement parts
Record symptoms, codes and radio presets. Park on a clean, hard, dry, level surface, select Park, apply the parking brake and chock the wheels. Let the exhaust cool. Compare the delivered six-pin/three-pin module connections and its formed lines with the original application. Set out both correct new tank seals, the proper rings, the new exhaust flange gasket and three new nuts. Confirm the complete special-tool, draining and support arrangements in the table.
2. Isolate the battery and release retained pressure
Turn the ignition and accessories OFF. Release the PCM wiring-harness retainer from the battery-box cover, then lift the PCM with its bracket out of the cover’s retainers and support it aside with its electrical plugs connected. Remove the cover screws and cover to reach the battery. Disconnect and isolate the negative side-terminal cable. The factory battery-access procedure does not require unplugging the PCM electronics.
With the battery isolated, clean the capped rail test connection and attach the correct gauge under a towel. Put the bleed hose in approved gasoline recovery and open its valve until system pressure is released. A no-start or silent pump does not establish zero pressure. Before removing the gauge, bleed fully, protect the fitting with a towel, collect residual gauge fuel and reinstall the rail-port cap. Put wet towels in the proper closed waste container. Follow the factory pressure-relief sequence.
3. Establish the safe fuel quantity
The tank may be removed only when no more than 11.4 L (3 U.S. gallons) remain. If the level cannot be reliably established below that limit, use the complete approved fuel-recovery setup first. The inoperative-pump method uses J42960-2 to hold the filler flapper open and the shaped J45004 siphon hose through its guide. Keep battery negative isolated and remove the filler cap before insertion.
Use only the specified hose shape/stiffness: the inlet check-valve cage can trap ordinary tubing. Feed the hose gently through the cage and never insert it past its fitting-end tag. Connect only the positively matched gasoline-rated extension/recovery equipment and use its approved pumping or siphoning method. Remove the special hose and holder afterward. This drains from the primary side; resolve an unreliable gauge or trapped secondary fuel before lowering. See GM’s tank-draining instructions.
4. Raise and secure the vehicle
Use the correctly installed, load-rated full-height frame-contact hoist selected for this route, and engage its mechanical locks. Follow the exact vehicle lift diagram and the lift manufacturer’s instructions. The illustrated front pads are approximately 310 mm (12.2 inches) inboard of the front pinch-weld flanges; the rear pads are 255 mm (10 inches) inboard. Locate the illustrated structural points; these distances are not permission to contact arbitrary floorpan areas.
Install the required support at the opposite end of the vehicle and the vehicle-to-hoist restraint for component removal. Confirm the tank handler’s complete operating-height range and underbody clearance. Keep all support equipment clear of the tank and exhaust removal paths.
5. Remove the rear exhaust assembly
Support the complete cool exhaust assembly with the two selected component stands and an assistant. Remove the three nuts at the catalytic-converter-pipe/rear-exhaust flange, separate the pipes and discard the gasket. Use the hanger-release pliers at the three rubber isolator locations without tearing them, then remove the rear exhaust assembly with adequate help. Inspect the sealing faces, studs and rubber isolators. Keep the sound isolators for reuse; reassembly requires a new gasket and three new nuts. Follow the factory exhaust removal.
6. Remove the EVAP canister
Record the original destinations of the fresh-air, vent and purge lines. Clean the closed connections before releasing them. Disconnect the canister fresh-air connection from the tank fresh-air pipe, the tank vent pipe and the chassis purge pipe. Support the canister, remove its underbody nuts and lower it just enough to unplug the vent-solenoid electrical connector, then remove it. The canister procedure keeps these three line functions separate.
7. Disconnect and lower the tank
Clean closed fuel/EVAP fittings with the selected controlled compressed-air equipment and wipes before opening them. The chassis fuel-feed joint is a metal-collar quick connection: remove its external retainer and use the correct 3/8-inch J37088-A-type separator to release its internal tabs. Catch residual fuel in the approved collection assembly with an opening at least 300 mm (12 inches) across. Protect clean open line ends with the correctly fitting temporary caps.
Release plastic EVAP fittings by their actual original latch style: squeeze the release tabs, move a Q-release tab across its slot, press both sides of a squeeze ring, or slide the retainer in its release direction. Do not apply the metal-line separator to these plastic latches. The metal and plastic connector procedures explain the distinct mechanisms.
Disconnect the filler hose and remaining vent/fresh-air connections at the tank. Unplug the tank harness and release its retainer from the rear frame. Position the matched 1758 handler and TJH10 jack, adjust the pads to the tank/heat-shield geometry and fully support the tank. Remove the metal tank straps and bolts without bending the straps, then lower carefully while checking every hose, wire and shield edge. As the tank clears the vehicle, fit and tighten the handler’s nylon restraint before further lowering or transport. Fully retract the jack before rolling it. The FWD route leaves the rear frame in place.
8. Open the secondary module first
Keep the removed tank stable and restrained against ring-release force. Clean the module areas. With both openings still closed, apply penetrant sparingly to both external ring tangs, allow it to work and remove excess. Keep spray out of the tank and off the seal grooves. Disconnect the secondary EVAP vent fitting, then use J39765-A and its correctly matched manual driver longer than 12 inches to unlock and remove the secondary ring.
Raise the secondary assembly only enough to unplug its level-sender lead and release the internal suction connection: press its tab and slide the connection downward. Lift slightly to disengage the orientation tabs, then rotate the module about 45 degrees as needed to withdraw it without bending the float. Preserve the secondary assembly for reuse, discard its old seal and protect the open tank from dirt. See the secondary-module procedure.
9. Remove the right primary pump
Disconnect the primary six-pin and tank-pressure-sensor three-pin plugs. Free its feed/vent lines from their molded routing and retainers. If an original sacrificial plastic line-retention strap must be cut, have the correct replacement retention ready first; the metal support straps are not cut. Do not pull on plastic pipes to lift the assembly.
With the tank securely restrained, use J45722 and the matching long manual breaker bar to turn the already-prepared primary cam ring counterclockwise. Lift the module slightly to release its orientation tabs, rotate it about 45 degrees to protect the attached float, then remove it with its internal transfer tube/lead. Discard the old primary seal. Inspect the tank sealing seats, retaining features and fuel condition; stop for the correct cleaning or repair method if contamination or damage is present. Follow the primary-module removal.
10. Install the primary and reconnect the secondary
Compare the new unit’s connector keys, formed line destinations, suction attachment and sender lead with the removed equipment. Keep its attached float intact. Fit the correct new primary seal dry, position the module with its orientation tabs aligned and install the correct new primary ring with the proper face upward. Use J45722 clockwise until the ring is fully seated in its retaining features. GM does not specify a numeric torque for this cam ring.
Reconnect the primary and tank-pressure-sensor plugs. Return the external pipes to their original grooves and retainers without kinks or strain. Connect the internal suction fitting fully onto the reused secondary pickup and confirm retention, then reconnect the separate sender lead. Install the secondary assembly with its own correct new dry seal and aligned tabs. Use J39765-A clockwise to fully seat its ring, reconnect its EVAP line and restore the molded routing. Confirm both hidden connections before closing the secondary opening.
11. Refit the tank, canister and exhaust
Remove and account for all temporary caps and external dirt shields. Raise the tank and heat shield with the secured handler while watching every connection and edge. Refit sound metal tank straps and tighten their body bolts to 25 N·m (18 lb-ft). Reconnect the rear-frame harness/retainer, vent and fresh-air lines. Connect the filler hose and tighten its clamp to 5 N·m (44 lb-in).
Reconnect the chassis feed fitting with the correct locking parts. GM specifies a small amount of clean engine oil at the male quick-connect end; snap it together, engage its retainer and pull-check it. That line-end oil does not belong in the tank seal grooves. Reinstall the canister, vent-solenoid plug and all three original hose connections; tighten the canister nuts to 9 N·m (80 lb-in).
Position the rear exhaust on its three sound rubber isolators. Fit the new flange gasket and three new nuts, tightening the nuts to 37 N·m (27 lb-ft). Confirm shield, pipe and harness clearance and sound retention before removing the temporary supports.
12. Restore power, prime and check the finished system
Lower the vehicle and add clean gasoline as required. Clean any existing corrosion at the negative terminal/cable contact, reconnect battery negative and tighten its bolt to 17 N·m (13 lb-ft). Install the battery-box cover and tighten its screws to 2 N·m (18 lb-in). Restore the PCM/bracket and wiring-harness retainers, radio presets and clock.
With the complete system closed, switch ignition ON for 5 seconds, then OFF for 10 seconds; repeat twice more. Inspect for leakage, then crank only as needed to start, never exceeding 20 seconds continuously. Stop for wetness or fuel odor. Verify the fuel-line/module connections, exhaust-flange sealing, level indication and original symptoms.
Complete the required delivery-pressure confirmation using the proper factory command/test conditions. Remove any test gauge with renewed pressure relief, contain residual fuel and restore the rail-port cap before driving. Recheck codes and operation; complete a Fuel Trim Reset only when it is required by the repaired P0171 diagnostic branch. An abnormal gauge reading or continuing EVAP/driveability problem still needs diagnosis.
Example of an in-tank pump assembly
Common mistakes that cause repeat work
- Ordering by model year alone: the 2006 Equinox first-design cutoff and the different Vue installation side matter.
- Pulling the primary before disconnecting the secondary: this can damage the hidden suction connection, sender lead or floats.
- Reusing either old rubber tank seal: both openings need their own correct new seal, installed without oil or sealant in the grooves.
- Using a short or mismatched ring driver: match both factory tools and retain the greater-than-12-inch secondary handle requirement. The tank must resist the manual release force.
- Leaving a pipe or retainer displaced: restore the molded line routing, internal suction latch, sender plug, EVAP connections and heat-shield protection before lifting the tank.
- Reusing exhaust sealing hardware: fit the new flange gasket and three new nuts, then check for exhaust leakage as well as fuel leakage.
Frequently asked questions
Why does replacing the right pump involve the other tank opening?
The primary and secondary assemblies connect inside the tank through a suction tube and electrical lead. The secondary unit must be lifted far enough to disconnect those connections before the primary can come out. Reuse the serviceable secondary assembly with its own correct new seal, then reconnect both internal connections.
Does this module fit every 2006 Equinox?
No. The selected product’s 2006 Equinox row specifies first design through chassis 66035231. Confirm the complete VIN, connector layout and original module with the supplier. The worked procedure here is specifically the 2005 FWD 3.4L vehicle.
Can I apply these steps to an AWD Equinox or a Saturn Vue?
Use the matching factory procedure. The AWD Equinox has additional propeller-shaft work, and the Vue lists the featured module on the opposite side. Sharing an aftermarket part reference does not make their access and reassembly steps identical.
Will a new pump fix P0171 or P0230?
Only if diagnosis establishes a related failure. P0171 has several air, fuel and sensor causes. P0230 identifies a relay-control circuit problem. Replacing the tank module before checking those alternatives can leave the original fault unchanged.
Do both seals come in the box?
Verify the delivered contents and exact seal dimensions/profile before starting. The listing includes sealing components, but its photographs show different quantities. This repair requires one correct new primary seal and one correct new secondary seal even when only the primary pump is being replaced.
Why is the fuel gauge wrong after the pump replacement?
Check the amount of fuel actually added and the primary/secondary electrical connections before assuming the new motor is faulty. A disturbed float or an unlatched internal sender connection can affect the indication. Diagnose the specific fault with the tank safely closed; do not repeat a tank removal on that symptom alone.
