update - not sure if anyone has found the problem. ours is currently in the shop. they do not seem to have any clue. can someone please tell me where the vent valve is physically located and where the solenoid is physically located, and finally where the canister itself is located. there is a check engine light... i believe is P0440 or P0446. anyone with any other info would surely help as we have been dealing with literally 25min fill up times....
