Support the fuel tank with a jack or a suitable support.
Remove the straps or bolts securing the tank to the vehicle.
Carefully lower the tank and disconnect the electrical connectors from the fuel pump assembly.

4. Replace the Fuel Pump

Remove the fuel pump assembly from the tank. This typically involves unscrewing the retaining ring.
Replace the old fuel pump with the new one, ensuring the O-ring is properly seated.
Reinstall the fuel pump assembly into the tank, securing it with the retaining ring.

5. Reinstall the Fuel Tank

Tools Required: Same as above.
Lift the fuel tank back into position and reconnect the electrical connectors.
Secure the tank with the straps or bolts previously removed.
Reconnect the fuel lines, ensuring they are properly seated and clamped.
