The procedure for removing the fuel tank is as follows, Slowly remove the fuel filler cap to relieve fuel tank pressure. Relieve the system fuel pressure. Disconnect the cable from the negative terminal of the battery. Loosen the left rear wheel lug nuts. Raise the rear of the vehicle and place it securely on jackstands. Remove the left rear wheel. Locate the fuel tank filler neck vent tube inside the left rear wheel well, disconnect the two-tab type quick-connect fitting. Disconnect the fuel tank filler hose from the metal tube at the upper end of the hose, not from the fuel tank. Disconnect the fuel line quick-connect fitting and the EVAP line quick-connect fitting, both of which are located at the front of the fuel tank. Disconnect the electrical connector from the fuel pump/fuel level sending unit. Support the fuel tank with a transmission jack or with a floor jack. Remove the fuel tank strap bolts. Carefully lower the fuel tank from the vehicle. Installation is the reverse of removal. Be sure to tighten the fuel tank strap bolts securely. When you're done, start the engine and check for leaks at any fuel line connectors that you disconnected.

The procedure for removing a fuel tank is much easier if the tank is empty. If the tank has a drain plug, remove it and drain the fuel into an approved container. If not, use a siphoning kit to remove the fuel. Start by relieving the tank pressure by removing the filler cap. Then, relieve the fuel system pressure and detach the battery cable. Raise the vehicle and secure it on jackstands. Disconnect the fuel lines and fuel filler tube, making sure to label them if needed. If there is no drain plug, siphon the fuel from the fuel feed line. Support the tank with a floor jack and disconnect the tank retaining straps. Lower the tank to disconnect the electrical connectors from the fuel gauge and pump. Finally, remove the tank from the vehicle. The installation process is the reverse of removal.

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. Extra caution should be taken in garages with natural gas-type appliances, as the pilot light could cause an explosion.

Cleaning the fuel tank (due to fuel contamination) should be performed by a professional with the proper training to carry out this critical and potentially dangerous work.
