Get a non-vented cap. Our EVAP and fuel systems are designed to vent through the canister so that less HC emissions escape from the tank.
Also, the non-vented kind don't go bad as often due to having less seals. The only seal you have to worry about is the outer o-ring and you can see when that is bad.
