LOL well that puts a whole different light................and I likely won't be much help. One big issue with "build your own" is that you can create a siphon situation if you are not careful.
Yeah, I’m trying to avoid that too. And like I said, keep junk and stuff from ending up in the fuel tank. I’m thinking at least a 1/2 vent, maybe just do it in 5/8 if I can find the room and several wraps around something that is 2 inches in diameter. I just need to stop junk from getting in there and I need some sort of check valve in case of a crash. I guess I should dish up an NHRA rule book and see what that says about venting a tank.
