Relieve the fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.

2. Remove Fuel Pump

Tools Required: Fuel line disconnect tool, screwdriver, ratchet set.

Lift the rear seat to access the fuel pump access panel.
Remove the access panel screws and lift the panel.
Disconnect the electrical connector from the fuel pump.
Use the fuel line disconnect tool to remove the fuel lines from the pump.
Unscrew and remove the locking ring securing the fuel pump assembly.
Carefully lift the fuel pump assembly out of the fuel tank.

3. Inspect and Replace Fuel Pump

Visually inspect the old fuel pump for signs of damage or wear.
Compare the old pump with the new one to ensure compatibility.
Install the new fuel pump into the assembly, ensuring it is seated properly.
Reattach the locking ring to secure the pump in place.

4. Reassemble and Test

Reconnect the fuel lines to the new fuel pump, ensuring they are secure.
Reconnect the electrical connector to the fuel pump.
Replace the access panel and secure it with screws.
Reconnect the negative battery terminal.
Reinstall the fuel pump fuse.
Turn the ignition key to the "ON" position to prime the fuel system and check for leaks.
