Disconnect the electrical connector from the fuel pump.
Carefully remove the fuel lines from the pump, using a line removal tool if necessary.
Unscrew the retaining ring or bolts that hold the pump assembly in place.
Carefully lift the pump assembly out of the tank.

4. Install the New Fuel Pump

Install the new fuel pump assembly into the tank, ensuring it is seated correctly.
Reinstall the retaining ring or bolts, tightening them to the manufacturer’s specifications (typically around 15-20 ft-lbs).
Reconnect the fuel lines and electrical connector to the new pump.

5. Reassemble the Access Panel

Replace the access panel and secure it with screws.
