Location of Vapor Canister Vent Solenoid on a 2007 Chevrolet

Recommended Posts

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.

Update ---- I followed the overfill hose down ~18" and around frame which was hiding part. It is located in front of rectangular canister which is immediately in front of the fuel tank. It is above rectangular canister and above frame so you really have to "feel" for it. Tough to get to when you are working on the ground but possible. Hose will allow positioning part to remove. Note that optional oval wiring adaptor is not needed on this model since replacement part and original both use same shape wiring connector. Because of awkward positioning and maybe my size and age, it was a three hour job including rewiring white power wire that was cut.


Thanks to those that thought about helping and to those that didn't give canned answer that really didn't fit specific application and did not respond, frustrating me further.


I hope this may help others especially with vehicle that dealers won't service being too large for their shops.
