  Q: How do you remove the fuel tank in a Toyota Highlander?

  A: To remove the fuel tank in a vehicle, start by relieving the fuel system pressure and disconnecting the cable from the negative battery terminal. Then, remove the Fuel Pump/Fuel Level Sensor. If the tank is full, siphon the fuel into an approved container. Next, raise the vehicle and secure it on jack stands. The steps for removing the fuel tank vary depending on the model and year of the vehicle. For 2007 and earlier models, remove the center part of the exhaust system and the driveshaft if applicable. Remove the fuel tank protector and heat shield, and disconnect the fuel filler neck hose and EVAP hoses. For 2007 RX 350 and all 2008 and later models, remove the front, center floor cover, and rear exhaust pipe assembly. Remove the center exhaust pipe assembly and exhaust pipe support bracket. For 2WD models, remove the fuel tank heat shield and charcoal canister protector plate. For 4WD models, remove the rear driveshaft, heat shield, and charcoal canister protector plate. For all models, support the fuel tank securely and remove the bolts from the fuel tank retaining straps. Carefully lower the tank and ensure all electrical harnesses, fuel lines, and EVAP system hoses are disconnected. Finally, lower the fuel tank to the ground and tighten the fuel tank strap bolts securely.

  Q: What precautions should be taken when repairing the fuel tank or filler neck?

  A: Any repairs to the fuel tank or filler neck should be done 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 the repair of the tank. If you are removing the fuel tank from the vehicle, do not place it where there are sources of heat or sparks. Be especially careful inside garages where a gas-type appliance is located, because it could cause an explosion.
