Charcoal Canister Help

i had mine capped off at the canister.fumes were really bad.the line comming from the tank to the canister was the only one connected the other 2 had caps on them,therefor venting the tank in the engine compartment.i hooked one of the capped off ones to the vaccume port on the carb,which pulled the fumes out of the tank and out the exhaust.no more gas fumes
