It would probably be worth it just to have it pull air from somewhere besides the side of the truck.
I was serious about the weather. It can be 90° and with the in-cab tank its probably 110°+ so of course its expanding and venting. Then a storm comes through, temps drop while it's raining and the cap opens up and starts pulling atmosphere.
This is the view the rain clouds have. This is the only atmospheric opening in the system.
Hell id be happy with some BS 70s smog charcoal canister.
