Hello:
I need to convert my 72 Cutlass gas tank to 1 line, 3/8" and no returns. Do I just plug the original return line and vents (3) and add a vented cap? Or what do I need to do? The outside is very good and the inside is like brand new!
Thanks again!

 

You can plug the return line with no problem, but why do you want to plug the vents? The non-vented caps have a different barb arrangement than the older vented caps specifically to prevent interchange, so you may be stuck with keeping a vent line.

 

Thanks Joe:
I just got back into town after 4 days.
I don't mind having a vent line attached at all. Which one do I keep, and do I hook it up the the ? thing bhind the back seat??Thanks Again

I am not a Rocket Scientist, but I would hook up all the vents, including three vent pipes above the rear axle.
