Hi All, just a weird question for you's. our 1967 olds 442 has 2 lines from the gas tank coming up to the fuel pump, main and a return, now for years I always though this would be a vented system because it has a return line right, well i have the red use premium gas cap on the gas tank it says non vented, ?? can somebody clarify this for me, thanks so much for any input, john....

 

What the cap is telling you is that it is a non-vented cap. The tank has vents lines that come up behind the rear bumper and the fuel return is not a venting system.

 

Thank you so much for clearing this up for me oldscutlass !! I saw those 2 vents in the back that you are talking about, Now it all makes sense to me thanks again buddy, john....................
