Raise the rear of the vehicle safely using jack stands.
Remove the fuel tank shield (if equipped) using a socket set.
Drain the fuel tank to a safe level to reduce weight and spillage risk.

3. Remove the Fuel Tank

Disconnect the fuel lines from the tank using a line disconnect tool.
Disconnect the electrical connectors from the fuel pump.
Remove the mounting straps or bolts securing the fuel tank to the vehicle.
Lower the fuel tank carefully from the vehicle.

4. Replace the Fuel Pump

Remove the fuel pump assembly from the tank by unscrewing the retaining ring.
Replace the old fuel pump with a new one, ensuring the O-ring is seated properly.
Reinstall the retaining ring securely.

5. Reassemble and Reinstall

Place the fuel tank back into position under the vehicle.
Reconnect the fuel lines and electrical connectors.
Reattach the mounting straps or bolts to secure the tank.
