- Torque wrench
- Safety goggles
- Gloves
Parts Required:
- New fuel pump assembly
- New fuel filter (if needed)
Ensure the vehicle is parked on a level surface and the engine is cool before beginning work.

2. Relieve Fuel System Pressure

Locate the fuel pump fuse in the fuse box and remove it.
Start the engine and let it run until it stalls to relieve pressure in the fuel lines.
Turn off the ignition.

3. Remove Fuel Pump

Disconnect the negative battery terminal to prevent electrical hazards.
Access the fuel pump by removing the rear seat or trunk panel, depending on the model year.
Disconnect the fuel lines from the pump carefully to avoid fuel spillage.
Unplug the electrical connectors from the fuel pump.
Remove the retaining ring or bolts holding the fuel pump assembly in place and lift out the pump.

4. Install New Fuel Pump

Place the new fuel pump in position and secure it with the retaining ring or bolts.
Reconnect the electrical connectors ensuring they are securely fastened.
Reattach the fuel lines, ensuring they are tight and leak-free.

5. Reassemble and Test

Reinstall the rear seat or trunk panel.
Reconnect the negative battery terminal.
Replace the fuel pump fuse.
Turn the ignition to the "ON" position without starting the engine to prime the fuel system, then check for leaks.
Start the engine and monitor for proper operation.
