Gasoline Smell....where is it coming from?...6 conversion, Update 5/18 Options

X2 on Jeff's comments - but you never told us if you are running a return line & old style 3-pipe pump -

if you have return fuel circulating it makes a LOT of vapor - cut off & plug the return line (at the tank) if you have one - it is totally useless on a carburetted car

- throw away or sell the oem pump & install a Facet - $40

be sure you have an open vent at the filler neck so the atmospheric psi can get back into the tank as you "suck" out fuel (that tiny pipe) - vent it overboard outside the trunk

throw away that canister

buy a new gas cap with decent seals - abt $35 from a 356 supplier

if still a problem, run a vacuum line from the big neck pipe to the intake manifold & suck out the fumes (that was the whole purpose of your canister & its lines) - your oem 4 had a suction line thru the body for that - hope you did not cut it off

On my conversion, I attached one vent line to the nipple on the engine shroud, and the other line leading to a fitting I installed on my rain hat air filter. This helped with the fumes by actually pushing and pulling air through the carbon canister. It was pretty bad before I got around to connecting the lines.

You did the right thing, George, and it was probably pretty easy to figure out and to do. I fail to see why this conversation still seems to be dancing around that solution .................

Put a "T" in the drain hose and connected the open hose to it.

Drove the car for 30 miles and no gas smell!

Thank you for all the advice.
