I’ve got a 03 2200. It has the oblong gas cap with the threaded screened fitting on the inside of the cap. If any of you have this type of cap can you tell me how the gas tank can vent with that kind of cap. I took the vent hose off at the tank and blew into it with the gas cap open and air came out at the cap end. I then closed the cap and blew into the vent hose and air and fumes came back. Make sense?
