Unscrew the retaining rings or bolts that secure the fuel pump assembly to the tank.
Carefully lift the fuel pump assembly from the tank; be cautious of any residual fuel.
Disconnect the fuel lines and electrical connectors from the pump.

4. Install the New Fuel Pump

Connect the new fuel pump to the electrical connectors and fuel lines.
Place the new fuel pump assembly into the tank and secure it with retaining rings or bolts.
Reinstall the fuel tank, ensuring all connections are tight and secure.

5. Reconnect Battery and Test

Reconnect the negative terminal of the battery.
Turn the ignition to the "ON" position (without starting the engine) to prime the fuel system and check for leaks.
Start the engine and monitor for proper operation.
