  Q: How to remove and install a fuel tank?

  A: Relieve the fuel system pressure. Disconnect the cable from the negative battery terminal. Raise the vehicle and securely support it on jackstands. Remove the fuel tank rock guard, if equipped. Locate the fuel tank filler neck hose, loosen the hose clamp on the fuel tank filler neck hose at the tank, then work the hose off the pipe and disconnect the filler neck hose from the tank pipe. Locate the EVAP line that goes from the tank to the EVAP canister and disconnect it from the EVAP canister. Disconnect the EVAP vent line from the EVAP canister. Disconnect any EVAP line clips attaching the line to the chassis. Locate the fuel line quick-connect fittings and disconnect them from the chassis lines. Disconnect the fuel and EVAP line quick-connect fittings. It's easier to remove the fuel tank when it's nearly empty. However, there is no fuel tank drain plug, so if there's still a lot of fuel in the tank, siphon or hand-pump the remaining fuel from the tank through the tank filler neck pipe into an approved gasoline container. Detach any clips that secure the Fuel Pump/fuel level sending unit harness to the crossmember or frame rail and detach them. Support the fuel tank. The fuel tank is retained by two transverse straps. The outer end of each fuel tank strap is secured to the vehicle by a bolt. The inner end of each strap is secured to a mounting bracket by a hinge. Remove the two fuel tank strap bolts, then disengage each strap hinge from its mounting bracket and remove the straps. Carefully lower the tank just far enough to access the fuel pump/fuel level sensor module, then disconnect the electrical connectors from the pump module and from the fuel tank Fuel Pressure Sensor. Lower the tank the rest of the way. Installation is the reverse of removal.
