Start with an empty fuel tank.
Disconnect the negative battery cable.
With the car on a lift or jackstands, remove the driver’s side rear wheel and inner fender
liner.
Using a file or wiz wheel with a Roll Lock sanding disk, prepare the exterior surface of the driver’s side
tank to be sure that the surface is flush and true.
Approximately 3 inches from seam and 2 ¾ inches from
