All repairs to the fuel tank or filler neck should be carried out by a professional with experience in this critical and potentially dangerous work. Even after cleaning and flushing the fuel system, explosive fumes can remain and ignite during tank repair. If the fuel tank is removed from the vehicle, it should not be placed in an area where sparks or open flames could ignite the fumes. Be especially cautious in garages with natural gas appliances, as they could cause an explosion.

The following procedure is much easier to perform if the fuel tank is empty. Run the engine until the tank is empty. Remove the fuel tank filler cap to relieve fuel tank pressure. If the vehicle is fuel-injected, relieve the fuel system pressure. Detach the cable from the negative terminal of the battery. If the tank still has fuel in it, you can drain it at the fuel supply line after raising the vehicle. Raise the vehicle and place it securely on jackstands. Disconnect all hoses and the electrical connector for the fuel gauge sending unit and electric fuel pump (if equipped). Carefully label all hoses so you can reinstall them in their original locations. Siphon the fuel from the tank at the fuel feed line, not the return line. Support the fuel tank with a floor jack or jackstands. Position a piece of wood between the jack head and the fuel tank to protect the tank. Disconnect the fuel tank retaining straps and pivot them down until they are hanging out of the way. Remove the tank from the vehicle. Installation is the reverse of removal.
