Re: Gas Tank

I just bought this cap from napa
https://www.napaonline.com/en/p/BK_7031220

Its meant for trucks without evaporative emision controls. Its vented, but only through a relief valve. I think that will be the case for most gas caps. So the tank will still build up some pressure, but the cap will relief at a preset pressure.
