To remove the fuel tank, it is recommended to do so when it is nearly empty. If that is not possible, try to siphon out the fuel before removing the tank. Start by relieving the fuel system pressure and disconnecting the cable from the negative battery terminal. Then, raise the vehicle and secure it on jackstands. If there is still fuel in the tank, disconnect the quick-connect fitting for the fuel inlet line and siphon or hand-pump the remaining fuel. Remove the exhaust pipe and muffler insulators, as well as the heat shield if applicable. Disconnect the electrical connector for the fuel pump/fuel level sensor module and the connector for the EVAP canister vent solenoid hose. Mark and disconnect the EVAP system hoses, as well as the fuel filler neck hose and fuel tank ground strap. Disconnect the fuel filter connectors and separate the lines leading to the tank. Support the tank with a transmission jack or floor jack, and remove the fuel tank strap bolts. Lower the tank and unclip or detach any remaining cables, hoses, or lines. Finally, lower the tank completely, angling it to clear the frame and exhaust pipe, and then remove it. The installation process is the reverse of the removal steps. It is important to note that when the battery has been disconnected, the Powertrain Control Module (PCM) must relearn its former driveability and performance characteristics.

During the installation process, follow the reverse of the removal steps to install the fuel tank. Ensure all connections, hoses, and lines are securely reattached. Also, remember that when the battery has been disconnected, the Powertrain Control Module (PCM) must relearn its former driveability and performance characteristics.

Prior to cleaning, it is important to remove the fuel pump/level sending unit module and all EVAP system components.

It is recommended to have the fuel tank steam cleaned to remove sediment from the bottom.
