Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative terminal of the battery to ensure safety.
Relieve fuel system pressure by removing the fuel cap and using a fuel pressure gauge.

2. Access the Fuel Pump

Remove the rear seat cushion and/or floor cover to expose the fuel pump access panel.
Unscrew the access panel and set it aside.

3. Remove the Fuel Pump

Disconnect the electrical connector from the fuel pump.
Carefully detach the fuel lines; have a container ready to catch any spillage.
Unscrew the retaining ring that holds the fuel pump in place using a special fuel pump locking ring tool or a hammer and chisel.
Gently lift the fuel pump assembly out of the tank.

4. Install the New Fuel Pump

Replace the old fuel pump with the new one, ensuring it is oriented correctly.
Secure the new pump in place with the retaining ring, using the appropriate torque specifications (usually around 30-40 ft-lbs; consult service manual).
Reconnect the fuel lines and electrical connector to the new pump.

5. Reassemble and Test

Reinstall the access panel and the rear seat cushion.
Reconnect the negative terminal of the battery.
Turn the ignition key to the ON position to prime the fuel pump and check for leaks.
Start the engine and ensure it runs smoothly.
