Fuel-pump replacement may be needed when a 2007–2009 Hyundai Santa Fe with a 2.7L or 3.3L gasoline V6 develops extended cranking, a crank-no-start, hesitation or stalling from inadequate fuel delivery. On the 2008 3.3L worked example, P0230 points to the fuel-pump primary relay circuit. Symptoms or a code alone do not prove the pump has failed: check electrical supply and fuel pressure before choosing this repair.
Which Santa Fe does this guide cover?
The product coverage below is for selected 2007–2009 Hyundai Santa Fe 2.7L and 3.3L gasoline V6 models. The installation walkthrough uses a 2008 U.S. Santa Fe Limited 3.3L AWD with the metal fuel-pump retaining ring. Its pump is reached through the cabin floor beneath the left second-row seat. The separate sender on the other side of the tank is a different component.
Match your VIN, engine, trim, original module reference, fuel fittings and electrical connectors before ordering. A listing that includes your model year does not automatically cover every trim or fuel system. Stop if your tank has a different retaining system or the new module does not match.
Planning estimates cover one pump module, a new tank seal and ordinary consumables. Time assumes a diagnosed fault, an undamaged access area and the correct tools. Diagnosis, damaged wiring, contaminated fuel, additional sender work and tools bought for this job are extra.
Fuel and cabin safety
Gasoline and its vapors ignite easily. Work with a cool vehicle in a well-ventilated location away from flames, heaters, cigarettes, sparks and operating electrical equipment. Park level, apply the parking brake and chock the wheels. Keep a suitable Class B fire extinguisher accessible. Wear eye protection and gloves selected for gasoline exposure.
Ensure the liquid fuel level is below the pump opening, protect the upholstery and prepare fuel-compatible containment before opening any fitting. Never use an ordinary shop vacuum, general-purpose electric transfer pump, power impact tool or grinding equipment around gasoline. Put contaminated wipes in a self-closing oily-waste container; it is not a liquid-fuel storage tank.
Relieve fuel pressure in the sequence below and isolate the negative battery cable again before opening the system. Residual fuel can still escape. If the engine will not run, the connector is heat-damaged, fuel sprays persistently, or the locking parts are badly corroded, stop and arrange controlled professional service.
Featured replacement fuel-pump module
A-Premium FP0054 is the electric in-tank module linked here, ASIN B075CBWHSL. The selected listing supplies one boxed assembly and lists the pump, fuel-level sending unit, strainer and pressure sensor. Its Hyundai reference is 31110-0W000. This is a replacement module for the listed gasoline applications.
Check the delivered sensor, connector, pipe layout and float against the original before starting. The selected listing specifies a pressure sensor, while the manufacturer’s sensor fields differ; resolve a missing or mismatched sensor with the supplier. The manufacturer lists no tank gasket, so have the correct new packing ready. A replacement lock ring, access cover and the separate opposite-side sender are not confirmed contents.

The 3.3L GLS and SE rows above are 2008 only. Transmission, drivetrain and assembly-country restrictions are not specified in the exact listing; confirm your configuration instead of assuming all versions fit. This page does not extend the product to diesel models, later engines or Santa Fe Sport.
Confirm the fault before buying a pump
- Record codes and freeze-frame before clearing anything. On the worked 2008 3.3L, P0230 concerns the fuel-pump primary relay circuit. Check its supply, relay control, wiring and grounds before condemning the module.
- For a crank-no-start, check battery cranking performance, fuel quantity, ignition and injector operation as well as fuel delivery. A pump sound does not establish correct pressure; silence can mean an electrical fault.
- Inspect the pump and pressure-sensor plugs for corrosion, loose terminals or heat damage. A burned connector needs a supported wiring repair; installing a new pump into it is not a complete repair.
- Separate fuel-level complaints from delivery problems. This tank has two level-sensing locations, so the opposite-side sender and wiring can affect the gauge.
For the 2008 AWD 3.3L, the service pressure check is 375–385 kPa (54.3–55.8 psi) at idle. The specified equipment is gauge 09353-24100, connector 09353-24000 and inline adapter 09353-38000 between the feed hose and delivery pipe. A generic code reader cannot measure this pressure.
Pressure testing opens a pressurized fuel connection. It requires controlled pressure release, the complete correctly assembled gauge, a pump-activation leak check before running, an idle measurement and an approximately five-minute shutdown pressure-hold check. Depressurize again before removing the equipment, restore the original feed connection and leak-test it. Use professional fuel-system diagnosis if you cannot perform that complete sequence safely; do not improvise battery jumper wires beside an open tank.

DIY versus professional cost
These are planning ranges in U.S. dollars, not current listing prices or shop quotes. A usable set of ordinary hand tools and safe fuel-handling equipment is assumed. Ask for diagnosis and an itemized quote before authorizing a pump replacement.
| Expense | DIY planning range | What it covers |
|---|---|---|
| Replacement module | $70–150 | One aftermarket assembly; verify exact fit and delivered contents |
| New packing and consumables | $40–80 | Correct seal, absorbents and minor supplies; damaged retainers cost extra |
| Additional tools | $120–300 for a modest missing-tool set | Assumes existing common safety and containment equipment; buying a complete kit or specialist diagnostic equipment costs extra |
| DIY parts and supplies total | $110–230 | Add only tools you do not already own |
| Professional labor allowance | $240–540 | Illustrative 2–3 billed hours at $120–180/hour |
| Professional installed allowance | $435–930 | Labor plus $175–350 parts and $20–40 supplies; diagnosis, taxes and additional repairs may increase it |
A gauge problem, connector repair or relay fault can require a different repair entirely. Do not use the price of a replacement module as a reason to skip diagnosis.
Replacement walkthrough: 2008 U.S. Santa Fe 3.3L AWD
This walkthrough is for the left-side pump module with a metal cam-type retaining ring. The passenger-side sender, tank straps and tank itself remain in place during normal access. A plastic threaded cover requires different tooling and instructions.
1. Prepare the vehicle and reach the service cover
Park and secure the cool vehicle as described above. Switch the ignition off and disconnect the negative battery cable. Release the left second-row seat mounting-bolt covers; move storage trim only as needed. Remove the seat assembly’s four mounting bolts with a 14 mm socket and lift the seat with assistance. Inspect for attached wiring before moving it; stop if an SRS connection would need to be disturbed without its specific isolation procedure. Do not remove seat-belt anchors or confuse their fasteners with the seat mounts.
Lift the carpet at the pump access opening. Carefully release the adhered cover with a nylon wedge, preserving the perimeter seal and wiring grommet. Wipe dirt from the still-closed module and nearby floor. Keep dirt and cloth fibers out of the fittings.
2. Relieve pressure and isolate the battery again
With the ignition off, disconnect the pump electrical connector while the fuel fittings and tank remain closed. Reconnect the negative battery cable, start the engine and let it idle until it stalls from the disconnected pump. Turn the ignition off, then disconnect and isolate the negative battery cable again before touching any fuel hose. Residual pressure and gasoline can remain after the stall.
If the engine cannot run, this stall method has not relieved pressure. Do not repeatedly crank it or assume the system is empty. Have pressure released using the correctly connected fuel-service equipment and a controlled collection method before continuing.
3. Disconnect the top fittings and release the metal ring
Position absorbent and fuel-compatible containment. Identify and disconnect the pump and fuel-tank-pressure-sensor plugs. Cover the feed connection with a clean cloth, release its proper retainer and separate it carefully; disconnect the vapor/vacuum quick connector as well. Protect the open fittings without pushing dirt inside. Stop for sustained spray or a damaged retainer.
Record the module’s orientation. For this U.S. metal ring, Hyundai’s CM procedure uses a brass drift and controlled manual hammer taps. Place the broad brass tip securely on a ring-driving tab and move the ring counterclockwise to release it. Do not hit the tank or plastic module, use a steel screwdriver, or operate a power tool near fuel vapor. Stop if the ring binds, deforms or the tank tabs are damaged.
4. Disconnect the internal suction tube before lifting out
Lift the module only far enough to reach the internal suction/transfer-tube connection. Release that connection before withdrawing the assembly; do not pull the tube tight or let it fall out of reach. Guide the float arm through the opening without bending it, let residual fuel drain into suitable containment and place the module in the catch tray. Remove the old packing.
5. Install the new packing and correctly indexed module
Inspect the tank sealing groove, ring and locking tabs. Resolve corrosion or damaged parts before assembly. Compare the replacement’s sensor, electrical fittings, float and suction connection. Install one new correct 31115-0W000 packing for the opened pump port; do not stack seals, reuse the old one or add household sealant.
Reconnect the internal suction tube before lowering the module fully: engage its clip positively and make a gentle retention check. Guide the float without trapping it and align the module with the tank’s locating features. Keep the packing seated evenly. Fit the metal ring flat and drive it clockwise through its locking travel with controlled brass-drift taps until every tank tab is captured at its fully locked endpoint. Confirm the ring is flat, the module cannot lift or rotate, and the seal is not pinched or protruding. Do not use a plastic-cover torque specification. Stop if the seal moves or the ring cannot seat evenly.
6. Reconnect, activate and check for fuel leaks
Reconnect the feed and vapor fittings, secure their retainers and gently tug each fitting to confirm it locks. Reconnect both electrical plugs, including the pressure-sensor plug. Keep the service opening accessible for inspection and remove tools and fuel-wet materials. With all fuel connections closed and secured, reconnect the battery negative clamp: fully seat the terminal with its top flush with the post, then tighten the nut securely without distorting the clamp and confirm it cannot twist on the post; stop if the clamp or cable is cracked or damaged.
Turn the ignition ON without starting; the pump runs for approximately two seconds. Switch off and repeat the key-on operation two or three times. Inspect every disturbed fuel connection and the module flange under pressure before starting. If dry, start and idle the engine, then inspect again. Shut off immediately for wetness, leakage or persistent fuel odor; isolate power and relieve pressure before correcting it. Do not close the hatch or drive until both checks pass.
7. Restore the cabin barrier and seat
After the system passes its leak checks, restore the service cover, continuous perimeter seal and wiring grommet. If the original body seal or cover is damaged, use the VIN-matched Hyundai cover and specified sealing material; do not leave an open path for vapors into the cabin. Lay the carpet and wiring back without pinching them.
Reinstall the left second-row seat with its correct mounting hardware. The CM seat-bolt specification is 43.1–64.7 N·m (31.8–47.7 ft-lb); Hyundai’s campaign uses 54 N·m (40 ft-lb). Tighten the four assembly mounting bolts with a torque wrench. Restore trim and verify seat latches, belt routing and accessible buckles. Check fuel-level operation and rescan for returning codes after the repair. Any fuel odor, wetness or loose seat means stop and correct the cause before driving.
Repair video: second-generation Santa Fe access
Kaswell’s Kappa’s approximately one-hour fuel-pump video covers second-generation Santa Fe access. Its description includes the 2007–2009 V6 vehicles and also later 2010–2012 vehicles with different engines. It also shows separate sender work, an additional operation outside this pump-only walkthrough. Use it to orient yourself to cabin access; follow this guide’s 2008 U.S. 3.3L application, metal-ring method and specifications. Product fitment remains limited to the table above.
Common mistakes to avoid
- Replacing the pump because of a fault code without checking the relay circuit, power, ground and fuel pressure.
- Removing the opposite-side sender when the job is the left-side pump, or pulling the module against its internal suction tube.
- Applying a plastic-ring tool or a plastic-ring torque specification to the U.S. metal retaining ring.
- Reusing a flattened tank packing, trapping it under the module or bending the float arm.
- Reconnecting only the pump plug and forgetting the pressure-sensor plug, vapor connection or a quick-connector retainer.
- Closing the access barrier before checking for leaks, or confusing seat-assembly mounting bolts with seat-belt anchor fasteners.
Frequently asked questions
Does the fuel tank have to come out?
The specified 2008 U.S. 3.3L installation uses the floor access opening under the left second-row seat. Tank removal is a different operation. Corrosion, damage, contamination or a different vehicle configuration may change the repair.
Can I replace only the pump motor?
The linked product is a complete module. A motor-only repair has separate compatibility, internal-hose and assembly requirements. Do not dismantle this replacement module unless its instructions specifically require it.
Will a new pump fix an inaccurate fuel gauge?
Not necessarily. The tank has separate level-sensing components. A fault in the other sender, wiring or gauge circuit can remain after replacing this module. Diagnose the level indication separately.
Can I reuse the seal or the retaining ring?
Install a new correct tank packing. Inspect the metal ring and tank tabs; replace damaged or badly corroded parts before assembly. A ring that appears installed but has not engaged every locking tab can leave the module loose or the seal compressed unevenly.
What if the new module looks different?
Do not force it into place or modify the connector. Compare the part reference, flange, sensor, float, fuel outlets and internal suction connection. Resolve the difference with the supplier using your VIN before opening the fuel system.
