Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shock.
Relieve fuel system pressure by removing the fuel pump relay and running the engine until it stalls.

2. Access Fuel Pump

Remove the rear seat and locate the access panel for the fuel pump.
Unscrew and remove the access panel to expose the fuel pump assembly.

3. Remove Fuel Pump Assembly

Disconnect the electrical connector from the fuel pump.
Carefully detach the fuel lines from the pump, using a fuel line disconnect tool if necessary.
Unscrew the retaining ring that holds the fuel pump assembly in place and lift the assembly out of the tank.

4. Replace Fuel Pump

Remove the old fuel pump from the assembly and replace it with the new pump.
Ensure all O-rings and seals are replaced to prevent leaks.
Reinstall the fuel pump assembly into the tank, securing it with the retaining ring.

5. Reconnect Components

Reattach the fuel lines and reconnect the electrical connector to the new fuel pump.
Replace the access panel and reattach the rear seat.

6. Final Preparations

Reconnect the negative battery terminal.
Reinstall the fuel pump relay.
Turn the ignition key to the "On" position without starting the engine to build fuel pressure; check for leaks.
