Disconnect the electrical connector from the fuel pump.
Use the fuel line disconnect tool to carefully detach the fuel lines from the pump.
Unscrew the retaining ring and lift the fuel pump assembly out of the tank.

4. Install the New Fuel Pump

Replace the fuel filter if equipped with the new pump.
Carefully position the new fuel pump into the tank, ensuring the O-ring is properly seated.
Secure the pump with the retaining ring, ensuring it is tightened to manufacturer specifications (usually hand-tight plus a quarter turn).
Reconnect the fuel lines and electrical connector to the new pump.

5. Reassemble and Test
