Remove the rear seat or access panel to reach the fuel pump access cover.
Unscrew and remove the access cover and disconnect any electrical connectors.

3. Remove the Fuel Pump

Tools Required: Fuel line disconnect tool, container for fuel spillage.
Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
Disconnect the fuel lines from the pump assembly using the fuel line disconnect tool.
Remove the retaining ring securing the fuel pump to the fuel tank using a hammer and punch if necessary.
Carefully lift the fuel pump assembly out of the tank.

4. Install the New Fuel Pump

Parts Required: New fuel pump assembly, O-ring.
Inspect the fuel tank and clean any debris before installation.
Replace the O-ring on the new fuel pump.
Insert the new fuel pump assembly into the tank, ensuring it is properly seated.
Secure the pump with the retaining ring, tightening it according to the torque specifications (typically 20-25 ft-lbs).

5. Reconnect Components

Reconnect the fuel lines and electrical connectors to the fuel pump.
Replace the access cover and secure it with screws or the rear seat.
Reconnect the negative terminal of the battery.

6. Test the System
