While packing my GMC up for the night, I stuck my head into the engine compartment to take a quick look around before closing it up. What I saw really surprised me...and not in a good way!

I had had issues with gas odor before, but always looked for it from below and never found anything. Tonight as I looked around, I saw this:

Sorry about the quality of the picture, I was reaching in with my cell phone. I will have a better picture tomorrow. I believe that is the vapor canister, and if you look closely enough you will see a large ragged hole in the top! I am pretty sure that the hole is NOT supposed to be there.

If it isn't the vapor canister, can someone tell me what it is? I will get closer tomorrow.

Is there an equivalent replacement available from NAPA or others? I can order from JimK, but would like to have it sooner.

If that is leaking, or dripping gasoline, it isn't the vapor canister fault. The problem is with the problem prone "Vapor Valve" in the left rear wheel well. That is supposed to keep liquid fuel from ever getting to the canister. They leak, fail, scerw-up all the time.

JimK sells a good one. Don't buy the NOS Corvette part.

Those were pretty generic within GM for several years. I assume your coach is not a California model. There should not be a hole in the top, although the bottom is open. These are not a common replacemnt part since they rarely go bad and even if they do, most people will care. Matt is correct about the vapor return valve but since the top of your cannister is broken open, you may be smelling it becuase of that alone. I would take it off and see if someone has one in stock or go to a pick & pull.
