Disconnect the electrical connector from the fuel pump.
Use a fuel line disconnect tool to carefully detach the fuel lines from the pump assembly.
Unscrew the retaining ring using a suitable tool (e.g., a hammer and a punch) and lift the fuel pump assembly out of the tank.

4. Install the New Fuel Pump

Replace the fuel pump with the new unit, ensuring that the seal is properly positioned.
Secure the fuel pump assembly back into the tank, tightening the retaining ring to the manufacturer's torque specification.
Reattach the fuel lines and electrical connector.
