Thanks, will look for that thread. Funny about the upside down truck.

The gas comes out the fill cap, not before it. The gas caps are flush with the truck body and are not behind a door.

I have a 1976 F250 Ranger XLT Camper Special with a 460 and dual tanks and am having problems with fuel leaking out of both tanks at the gas filler cap. The gasket seals seem to be ok, but after driving it for about 10 minutes or more, pressure builds and gas slowly oozes out and has damaged...
