What is the recommended service for a plastic fuel tank that is leaking or damaged on GMC Sierra?

The fuel tank is made of plastic and cannot be repaired if it leaks or gets damaged. The only approved service is to replace the entire tank. To remove sediment from the bottom of the tank, it is recommended to have it steam-cleaned. Before cleaning, it is important to remove the fuel pump/level sending unit and all EVAP system components. After cleaning, allow sufficient time for the tank to air-dry before putting it back into service.

How to remove a fuel tank on GMC Sierra?

To remove the fuel tank, first disconnect the cable from the negative battery terminal and relieve the fuel system pressure. Then, raise the vehicle and remove the fuel tank rock guard if equipped. Loosen and disconnect the fuel tank filler neck hose and EVAP system vent hose, as well as the EVAP line that goes to the EVAP canister and the fuel supply line quick-connect fitting at the front of the fuel tank. If there is still fuel in the tank, siphon or hand-pump the remaining fuel through the tank filler neck pipe. Detach any clips securing the fuel pump/fuel level sending unit harness and support the fuel tank. Remove the two fuel tank strap bolts and disengage each strap hinge from its mounting bracket before carefully lowering the tank to access the fuel pump/fuel level sensor module and disconnecting the electrical connectors. To install, simply reverse the removal steps.
