Stock tank vent line

OK guys I need some help... I have and realize the tank vents go up the B pillar and back down thru floor.... My question is what kind of "filter" or stop do I put on end of fuel vent line under truck... I don't have canister/smog etc stuff and just need to vent the tank outside the cab without vapors getting into the cab!

TIA for answers!

Re: Stock tank vent line

I personally would plug the line at the tank and install a vented cap on the filler neck. I'd do it this way, as it eliminates some flex hose. You could actually cap the line under the truck where it heads to the vapor canister instead of pulling the seat. You'd still need a vented cap.
