š§ XT5 - Fuel Pump Replacement
On your XT5, the fuel pump is part of an in-tank fuel pump module (it includes the pump, level sender, and usually the fuel pressure sensor/regulator). Replacement method depends on whether your XT5 has an interior service access cover or if the fuel tank must be lowered.
Difficulty Level: Advanced | Estimated Time: 2.5-5.0 hours
ā ļø Safety & Precautions
- ā ļø Gasoline is extremely flammableāwork outdoors or in a well-ventilated area, away from heaters/sparks.
- ā ļø Relieve fuel pressure before disconnecting any fuel line to avoid spray.

- ā ļø Support the vehicle with jack standsānever rely on a jack alone.
- ā ļø Keep a class B fire extinguisher nearby.

HowToo sells all the parts you need for this repair (final list depends on your build):
- Fuel pump module assembly - Qty: 1
- Fuel pump module seal O-ring - Qty: 1
- Fuel line retaining clips - Qty: 1
š Before You Begin
- Park on level ground, set the parking brake, and chock the rear wheels.
- Try to drive until the tank is under 1/4 full. A lighter tank is much easier and safer if it must be lowered.
- Plan to clean the area around the pump lock ring before opening the tank so dirt doesnāt fall in.
- I need 2 quick details to give you the exact XT5 procedure and torque specs:
- ā Are you FWD or AWD?
- ā When you lift the rear seat bottom, do you see a round/oval metal access cover (service panel) in the floor above the tank?
šØ Step-by-Step Instructions
Follow these steps in order:
Step 1: Confirm which method applies (access cover vs tank drop)
- Use a trim removal tool set to lift the rear seat bottom edge and check for a service access cover.
- If there is no cover, the tank typically must be supported and lowered to remove the module.
Step 2: Pause here so I can give the exact procedure
- Reply with: FWD/AWD and Yes/No access cover.
- Once you answer, Iāll provide the complete step-by-step sequence with the correct disconnect points, lock ring method, and Torque to XX Nm (YY ft-lbs) specs for your XT5.
ā After Repair
- Cycle the ignition to prime the system (key ON a few seconds, OFF, repeat) before cranking.
- Check for fuel leaks at the module seal area and every line connection.
- If the check engine light comes on, scan for codes and address any EVAP/fuel pressure codes.
