Hi all,
I have a '69 'Vert with a problem on the fuel tank vent line. I got it with a new reproduction tank and the vent line spews fuel if it gets over half full or is hot outside.
What does it connect with or do I just cap it off? Thanks for your help. Mark

Welcome Mark,
There is no vent line on a 69', the gas cap is vented.
Sounds like you have a sending unit for a 350 SS or a big block motor which had a 1/4" fuel return line. Look along your frame (passenger side) and see if the car has two steel fuel lines. If you don't have a return fuel line simply drop the gas tank and plug the 1/4" line coming out of the sending unit.

Good Luck

Thanks for the reply. That is what I tried to do. I used a piece of vacuum hose and those small stainless clamps. It leaks when it gets real hot. What would you suggest for the cap?

Don't use vacuum hose to cap off. Try to find a better way using fuel line hose and a plug.

Use a vented gas filler cap as Drew suggested.

Or just get the sending unit for a Z28 that only has one pickup for a 3/8' line.
