I have posted this before: I put a new tank in my 68 fastback, "along w/every thing else", it had a vent line coming out beside the 3/8 pick up, in addition to the one going to the filler tube.
I routed the the front one (probly was supposed to go to a vacuum canister), around and up thru the trunk floor, "up high" , put a couple of coils in it and ran it down thru the trunk floor below the frame rail , it hasn`t splashed over yet at the gas pumps, I still put a masking taped piece of clear plastic under the filler opening , taped up tite to the opening , longer than the fender. I had a new form S barracuda in 1968 that would puke out back then , stock!.
