Fuel pump replacement on selected 2004–2006 Ford Ranger 2.3L, 3.0L and 4.0L gasoline trucks begins with diagnosing long cranking, a crank/no-start, stalling or weak acceleration. Lean-condition codes such as P0171, and P0174 on a two-bank V6, can accompany a fuel-delivery problem, but intake leaks and other faults can produce similar symptoms. Neither a code nor pump noise proves that the pump has failed. This guide concerns the featured module listed for 125.7- or 125.9-inch wheelbases, with 2005 Ranger fitment restricted to 125.7 inches; selected Mazda B2300, B3000 and B4000 applications are separated below.
Start with the certification label, engine, build date and original module identification. This is a diagnosis and replacement-planning guide, not a universal bolt-by-bolt procedure for every Ranger or Mazda truck. The tank, fuel-line connections and module retention must match the exact truck before disassembly begins.
Advanced; gasoline-service and safe lifting experience
3–6 hours after diagnosis; longer with corrosion or damaged fittings
$100–$250 for the module and matched small parts; not a live product price
Work with a cool vehicle in a well-ventilated area without smoking, flames, heaters or spark-producing equipment. Wear chemical-splash goggles and gasoline-compatible gloves. Fuel can remain pressurized with the engine off. Isolate the battery and relieve pressure using the exact vehicle procedure before opening fuel connections. Use gasoline-rated recovery equipment and a suitable grounded receiving container; an oil-drain pan, shop vacuum or improvised electric pump is not a substitute.
Tank removal requires stable vehicle support and separate, secured tank support. The high-lift jack combination below requires a vehicle hoist with its mechanical locks engaged; it is not a low-jack-stand setup. Stop for unstable support, severe corrosion, leaking lines, damaged mounting points, uncontrolled fuel release or an inability to identify the correct connector and retaining-ring procedure.
Featured fuel-pump module
Brand: A-Premium. Product: electric in-tank fuel-pump module assembly with fuel-level sending unit. Featured ASIN: B07B787Q4C. Selected application: the Ford Ranger/Mazda B-Series gasoline module associated with the wheelbase and production restrictions below. The product description lists one assembly, a sending unit, strainer and seal ring. Compare the supplied seal with the tank opening before installation; do not assume every accessory shown in a listing is included.
Listed interchange references include 6L5Z9H307CA, 6L5Z9H307F, 1F8113350B and E2363M. These are cross-reference identifiers, not an assertion that this aftermarket unit is a genuine Ford part. A similar-looking housing or an overlapping year range does not establish an electrical, tank-height or float-arm match.

Vehicle compatibility: match more than the year
The following are seller-listed applications, not a claim that every truck carrying these model names fits. Have the supplier match the VIN, build date, cab, wheelbase, tank and original module reference before purchasing. Do not extend this gasoline listing to diesel, flex-fuel or other configurations without specific catalog support.
| Vehicle | Listed years | Gasoline engine | Important restriction |
|---|---|---|---|
| Ford Ranger | 2004 and 2006 | 2.3L I4; 3.0L or 4.0L V6 | 125.7- or 125.9-inch wheelbase; match the original module and tank configuration. |
| Ford Ranger | 2005 | 2.3L I4; 3.0L or 4.0L V6 | 125.7-inch wheelbase only in the more restrictive listing description. |
| Mazda B2300 | 2004 | 2.3L I4 | Extended cab only. |
| Mazda B3000 | 2004–2006 | 3.0L V6 | Extended cab; listed production cutoff May 1, 2006. Confirm a truck built near the cutoff individually. |
| Mazda B4000 | 2004–2006 | 4.0L V6 | Listed production cutoff May 1, 2006; confirm cab, tank and original module. |
Do not round a wheelbase measurement into a fitment decision. Read the vehicle label and obtain a configuration-specific parts match. Transmission and drivetrain should be included in that check rather than assuming this table approves every combination.
Symptoms, fault codes and diagnostic checks
Preserve the evidence first. Record stored and pending codes, freeze-frame information, fuel level and whether the problem occurs cold, hot, at idle or under load. Do this before battery disconnection or code clearing. A vehicle that cranks normally but does not start needs ignition, injector-control and fuel-delivery checks, not an automatic pump replacement.
Separate lean codes from a pump diagnosis. Ford bulletin 04-17-4 includes the 2004 Ranger and discusses lean-code diagnosis when a vacuum leak is present. Check intake and vacuum connections and compare fuel-trim behavior under the specified test conditions. Replacing a pump will not repair unmetered air entering the engine. A four-cylinder engine does not gain a second cylinder bank because a generic code list mentions P0174.
Check delivery and the circuit together. Obtain the correct pressure-test specification and test conditions for the exact engine. Use a gasoline-rated gauge with the proper fitting; a gauge’s maximum scale is not the vehicle’s required pressure. Low delivery calls for inspection of supply voltage, grounds, connectors, the fuel filter and line restrictions before condemning the module. A basic multimeter or code reader does not replace the wiring diagram or a complete pressure test.
Treat gauge faults separately. An erratic fuel-level reading can involve the sender, its wiring or the instrument circuit. A complete module may contain the sender, but a dashboard reading alone does not establish failure of the pump motor. Fuel odor or visible wetness is a stop-driving concern, not a reason to continue testing a leaking system.
Tools, parts and supplies
Buy only equipment needed for the selected service route. General tools below are exact listings, while vehicle-specific seals, retaining hardware and connection adapters must match the truck. Tool capacities are not vehicle torque or pressure specifications.
| Tool or Supply | Exact Product | Product Link | Purpose and Selection Check |

| Spill control and line protection | Gasoline-compatible gloves, absorbents, lint-free cloths, fitted caps and approved waste container | Choose fuel-compatible materials and port sizes | Protect skin, keep debris out of openings and handle contaminated materials safely. Replace damaged connector retainers rather than improvising repairs. |
DIY versus professional cost
These are illustrative planning allowances, not current listing prices or shop quotes. Allow $100–$250 for the module and matched small parts, plus approximately $20–$60 for consumables. With suitable tools and facilities already available, that produces a $120–$310 parts-and-consumables budget. Additional hand and diagnostic tools may add $100–$300; hoist access, a fuel-recovery system and tank-support equipment are separate and can make a one-off DIY job uneconomical.
For a transparent shop comparison, an assumed 3–5 billed labor hours at $120–$180 per hour gives $360–$900 in labor. Combining that with the same $120–$310 materials assumption gives $480–$1,210 before taxes, fees or repairs to a damaged tank, straps or lines. A shop may supply a different part at a different price and use a different labor allowance. Request an itemized quote instead of treating these calculations as a local estimate.
Replacement work: preparation through final checks
1. Establish the fault and the exact service route
Complete the electrical and delivery checks, record the truck’s configuration, and compare the replacement identification with the original. Obtain the matching tank-removal and module-installation procedure, including connector releases, ring tooling, seal requirements and every disturbed fastener’s specification. Do not begin disassembly with those items unresolved.
2. Remove residual fuel pressure safely
For the 2004 Ranger 2WD 2.3L VIN D, Ford’s pressure-release instructions first disconnect the battery ground cable, then connect the proper gauge at the fuel-rail Schrader port. The gauge’s manual valve is opened slowly to collect discharged fuel in a suitable container. This does not require the engine to run. Follow the gauge manufacturer’s connection instructions, keep the bleed hose controlled, and do not confuse removing the fuel cap with relieving pressurized fuel lines. Use the corresponding engine procedure for other applications.
3. Prepare the lifting and draining equipment
Drain the tank using approved gasoline-recovery equipment before attempting to remove it. Position the hoist at the vehicle’s approved lifting points and engage the mechanical locks. Bolt the compatible tank handler to its jack using the handler instructions, then adjust the pads to the tank rather than balancing it on a small bare saddle. Fuel weight and an off-center load can destabilize an otherwise adequately rated jack.
4. Release the tank and its connections in the prescribed order
The tank must remain supported while its retaining hardware is released. Identify the filler, vent, fuel and electrical connections and provide enough controlled clearance to disconnect them without stretching anything. Use the correct release method for each fitting; pulling harder is not a substitute for releasing a retainer. Cap open fuel connections, account for residual fuel, and stop if a line or tank mounting point is damaged. Do not cut an access hole in the truck bed.
5. Compare and exchange the module
Clean the area around the tank opening before removing the module. Note orientation and carefully guide the float through the opening without bending it. Compare connector keys, outlet positions, module height, locating features and sender movement. A mismatch is a reason to stop, not to bend the sender or modify the wiring. The replacement needs the correctly specified new sealing material and retention procedure; do not substitute a torque from an earlier Ranger guide.
6. Reassemble without trapping hoses or wiring
Restore each connection to its original routing and confirm that its retention mechanism actually locks. Raise the tank slowly while checking for pinched lines and wires. Tighten tank, shield and related hardware to the exact application specifications with the appropriate tools. When transporting the removed tank on an OTC handler, secure the tank with the supplied nylon strap and fully lower the jack before moving it.
7. Check the completed fuel system before driving
Close the fuel system, restore clean fuel and clear spills before reconnecting power. Follow the applicable priming procedure and inspect the module seal, fuel fittings, filler and vent connections for leaks before starting. Check again with the engine running only after the initial inspection is dry. Verify pressure against the correct specification, check fuel-level indication and confirm the original complaint is resolved. Stop for wet fuel, strong persistent odor or an unsecured tank. Recheck after a short, safe road test.
Common mistakes
- Ordering by model year while overlooking the 2005 wheelbase restriction or a Mazda production cutoff.
- Replacing the pump because of a lean code without checking for intake leaks and electrical faults.
- Using an oil-drain pan for gasoline, opening a pressurized line, or balancing a tank on an unsuitable jack.
- Installing the wrong seal, bending the float, forcing plastic fittings or leaving connectors unsecured.
- Using another model year’s torque figures, or skipping the stationary leak check before a road test.
Frequently asked questions
Does this fit every 2004–2006 Ranger?
No. Wheelbase and the 2005-specific restriction matter. Match the VIN, tank, engine and original module before ordering.
Can a pump fail without a fault code?
A code reader alone is not a complete fuel-delivery test. Diagnose the actual starting or running complaint with the proper electrical and pressure checks rather than requiring a particular code before testing.
Can I use the older Ranger guide’s specifications?
No. The 2002 Ranger 2.3L, 112-inch-wheelbase guide covers a different featured module and vehicle configuration. It is not the service specification for this application.
Is a complete module the same as replacing only the pump motor?
No. The featured listing includes a module and fuel-level sender. Match the complete assembly and its connectors; do not assume a bare pump motor includes the same components.
When is a repair shop the better option?
Choose a qualified shop when safe lifting and gasoline-recovery equipment are unavailable, corrosion threatens the tank or lines, or the diagnosis and exact installation requirements are unresolved.
