The procedure is much easier to perform with an empty fuel tank, which may have a drain plug for this purpose; if not, siphon the gasoline into an approved container. Begin by removing the fuel tank filler cap to relieve pressure, then relieve the fuel system pressure. Detach the negative cable from the battery and siphon any remaining fuel into an approved container if necessary. Raise the vehicle securely on jackstands, then remove the heat shield, skid plate if equipped, and the front retaining strap. Support the fuel tank with a floor jack or jackstands, using a piece of wood to protect it. For 2010 and earlier models, remove the bolt from the rear retaining strap and pivot it down. Loosen the screw clamps at the fill pipe and vent pipe, disconnecting the pipes at the tank. Lower the tank enough to disconnect all vapor valve, fuel line, and electrical connectors from the sender unit, vapor valve, and fuel pump module as equipped. Clearly label hoses and fittings to simplify installation, and plug them to prevent leakage and contamination. For 2011 models, remove the fuel pump module cover to access some connectors. Disconnect any remaining connectors for the fuel pump, fuel gauge sending unit, or Fuel Tank Pressure sensor at the rear of the tank, then remove the tank from the vehicle. Installation follows the reverse order of removal, with new tank retaining strap bolts recommended, and for 2011 models, tighten the fuel pump module cover nuts to 80 in-lbs.
