So the evap smoke machine was a massive fail... Not a single sign of smoke. However, fill up the car, park on an incline and fuel just spits out the back of the tank.
Ends up being the hoses at the rear of the tank, which I am pissed about because they're not only brand new, but if I tight down the hose. Clamps any more, I'm gonna crush the tank nipples.

Just gonna order some softer and thicker walled hose. Does any know the hose diameter for the 1978-1979 filler and vent hose diameter?
