Thanks, but I think you are talking about Bruce and his build "Its Just A Pickup". THAT man has some skills and his work is definitely picture worthy.

I've done a little gas cap sleuthing and figured out what a "vented gas cap" is and how it works. Everyone else may already know, but after disassembling it I realize that there is a one way check valve which allows air to be drawn in (to relieve the vacuum pressure of emptying the tank through using up the gas).
This valve will not allow fumes to be vented out into the air. It will be a piece of cake for me to just remove the check valve and dab some sealant in the air holes to keep any air from coming or going. My question is though, do I want to do this? Does a new truck cap completely seal or does it also let air in to relieve vacuum pressure just like the old one? I could try it unmodified first and see what happens, but now I am curious. Who's got an answer?
