How do you remove a gas tank from a 99 Honda civic?

Answer 1

The gas tank is under the vehicle below the rear seat. You can access the top of the tank and the fuel pump by simply removing the rear seat, which is held down by two clips, one on each end of the seat and a bolt located at the rear of the seat between it and the seat back. Remove the bolt and then pry up the seat at the front. You'll need to do this to disconnect the wiring even if you have to remove the tank because of a leak or other damage. For fuel pump removal and replacement, remove the wiring and disconnect the fuel line, and remove the attachment bolts from the tank cover and lift it out. The pump comes with it. Replace the pump and the cover gasket and put it back in. To remove the tank, disconnect the wiring and fuel line, lift the vehicle on jack stands or a hoist, disconnect the metal bands under the tank at one end and let it drop slowly. Its best to remove the tank when emply and with the cover plate on. Work only in a well ventilated area, NO SMOKING OR SPARKS! Do not use electric tools.
