Fuel tank venting opinions

[Che70velle]

Trey, I contacted Tanks upon receiving mine, and asked this same question. The vent that they send will only allow venting inwardly, which is fine since the tank needs this as the pump is pumping outwardly. I was concerned that perhaps I needed a vented gas cap, and the tech told me absolutely not.
There is no way that the supplied vent they send can allow fumes to enter the garage. It's a one way vent, and works well on mine, with no fumes in the shop at all. Make sure you mount it higher than the tank, and your golden.

Thanks Scott and Ultimate. I need to look at my canister again. I believe I have three line connections.

I must have gotten a defective check valve or something... when I put my nose to it I could literally smell the fuel vapors coming out of it.

Any rate, check valve or no, I still prefer the factory set up.

I use II Much Fabrication vents and they work well.
