when I changed my ex wifes canister in her 04 suburban it was bone dry, the problem was still present immediately afterwards, it has been a little while since I have checked it, presuming I pull it again and it has gas in it, then how do I deal with this "vent"97% of the time that’s problem. Vent went bad and pulled gas in to canister. Pull canister and shake and see if has fluid in it
