fuel smell

Hi guys, I have a 58 apache I just put a zz6 crate engine and a fitech setup with a in tank aeromotive pump. Its bagged so it has a rear fuel cell. I went to speed shop and got check valve with small kn filter for fuel tank vent, but I am getting fuel vapor's filling the garage. What can I use for vent that wont let the vapor's escape?

I ordered the 11 much fabrication setup hope fixes issue

Re: fuel smell

We just hashed the same issue over on a rig on the Hamb with the same problem. Answer is the same. A charcoal cansiter out of a mid 70's GM should be easy to find and I've never heard of anyone replacing them because they went bad. You do want to replace the little filter pad that goes on top though. Tuck it in up front (find one the right size) and run the lines and put a non vented cap on the rig.

Re: fuel smell

I did find that you can buy new vapor canisters I actually found more on Amazon than on the parts house sites.
It's one of those things on the list for my 48's rebuild as the way it is setup with the filler in the bed it reeks of gas all too often.

Re: fuel smell

Here is what I did on my FiTech equipped '50 pickup. Ran a fuel line from a nipple in the filler neck (inside cab) looped high into the cab corner, then down through the floor, into the frame and back over the rear axle, ending in a regular clear plastic fuel filter. Vapor smell in garage is GONE.

Re: fuel smell

I can tell you my recent experience. The fuel lines were braided steel and the house inside was slightly deteriorating and allowing vapor to escape through the braided line. Teflon fuel lines fixed it.
