On fuel injected models, relieve the fuel system pressure. Remove the fuel tank filler cap to relieve fuel tank pressure. Disconnect the cable from the negative terminal of the battery. If equipped, remove the fuel tank drain plug and allow the fuel to drain in an approved gasoline container. On later models, use a siphoning kit to siphon the fuel into an approved gasoline container. Raise the vehicle and support it securely on jackstands. On 2006 and later models, unbolt and lower the center section muffler and exhaust pipe. Disconnect the fuel hoses or lines and the vapor return line. Clearly label, then detach the fuel feed, return, and vapor lines. Be sure to plug the hoses to prevent leakage and contamination of the fuel system. Support the fuel tank with a floor jack. Place a wood block between the jack head and the fuel tank to protect the tank. Remove the fuel tank strap bolts and the fuel tank protector if equipped. Swing the fuel tank retaining straps down until they are out of the way. On 1994 and earlier models, lower the tank enough to disconnect the electrical connector from the fuel gauge sending unit, which is located on the upper right side of the fuel tank. Remove the tank from the vehicle. Installation is the reverse of removal. To replace the overfill limiter (two-way) valve, remove the overfill limiter mounting bolt. Detach the vapor hoses from the limiter and remove it. Installation is the reverse of removal.

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 careful in garages with gas-type appliances, as they could cause an explosion.
