Thread: gas tank rollover valve

Tweet

Any ideas for a gas tank "rollover valve"? I'm trying to build some safety into my new rally car (for obvious reasons).

My filler cap is an aluminum flip-top on the fender, and I need a way for the tank to continue holding fuel with the car inverted and the cap ripped off.

I need to buy one, or have an idea how to build one.

Check on Speedway motors and such..
Nascar,ASA and most circle track cars use those valves so they cant be that hard to find on the net.
might also check Lefthander chassis, Affco, ATL fuel cell's,.......

from ATI, they make fuel cells. Thank you.


I don't want to ask and not acknowledge my answers, I would have to face Street's wrath.
