I have a PO449 and suspect the vapor canister and vent solenoid need replacing, especially since fuel dispenser keeps clicking off when refueling (I'm told overfills have returned back to canister and carbon goo is now causing this system). I have the replacement part in hand but cannot find item on the RV; I see where the vent hose runs downward from the fuel filler but is hidden by frame and the humongous fuel tank. I got to believe that GM has made this part somewhat easy to get to but I can't find it. Any qualified suggestions as to where to find it and please, no guesses based on a pickup....this is the 35000 Express cutaway used for small Class B RVs. All previous threads were on the pickups and SUVs so I have the procedure down but nothing on part location specific for my vehicle. Thanks!
