2. Remove the Fuel Tank

Relieve Fuel Pressure: Remove the fuel pump relay from the fuse box and start the engine until it stalls to release fuel pressure.
Disconnect Battery: Ensure the negative battery terminal is disconnected.
Raise Vehicle: Use a jack to lift the vehicle and place it securely on jack stands.
Remove Fuel Tank Straps: Use a socket set to unbolt and remove the fuel tank straps that secure the tank to the vehicle.
Disconnect Fuel Lines: Carefully disconnect the fuel lines from the fuel pump assembly, using pliers if necessary. Be prepared for some fuel spillage and have rags ready.
Lower Fuel Tank: Carefully lower the fuel tank from the vehicle.

3. Replace the Fuel Pump

Remove Fuel Pump Assembly: Disconnect any electrical connectors and remove the locking ring that holds the fuel pump assembly in place. Carefully lift the assembly out of the tank.
Install New Fuel Pump: Position the new fuel pump into the fuel pump assembly. Ensure it is seated properly and secure it with the locking ring.
Reconnect Electrical Connectors: Reconnect any electrical connectors to the fuel pump assembly.

4. Reinstall Fuel Tank

Position Fuel Tank: Raise the fuel tank back into position under the vehicle.
Reconnect Fuel Lines: Reconnect the fuel lines, ensuring they are secured and there are no leaks.
