    Umm, thanks, but no. It's not actually part of the canister (unless it ships with the canister) , and it's not under the gas tank. It is visible from the right rear fender well looking in at the canister. Yes, I finally found it. Looks like lowering the X-member will be the easiest way to gain access. I'll post a pic if I can ever find a replacement. What a PITA!

    Talked to dealer parts guy, who cannot find a part number - nor the part. If it has a code, you would think it had a part number...
    gotta a PM to Greg@pace. HELP!

    Looked very much like this. I won't have a opportunity to remove it until this weekend.

    OK, There is light at the end of the tunnel. To all that have tried to help - Caddy parts guy, Greg@Pace, and all of the GM parts guys I have talked to - (I must have been the only G8 ever with this code), I thank you. The evap Vent Solenoid is indeed a separate piece than the canister. It is not in the G8 parts bin. The GTO one (and probably others, as 2 local dealers had this in stock) fits fine.

    You can see that they are identical, in physical dimension and stampings.
    here is the part number off of the box. It cost me $41. I know that I could have got it for $32 but it's the only one I could find on the weekend.

    I had to lower the right side of the rear cradle by loosening all 4 X-member bolts. A little prybar magic and I had enough room for my hands. I actually broke the old one apart trying to free it from it's bracket. This, however, gave me a better sightline to remove the part.

    Look closely and you can see the canister further in about a foot from the vent.

    I hope that this helps someone else. It was a major pain in the ass trying to find a part that no one thought existed! Sorry for the crappy dark pics, but you should get the idea.
    Cheers!!

    I'm getting the same code and, of course, I'm out of the warranty with 55k miles. Did you test the valve in any way? I see the "currently dead" caption in one of your photos, but didn't see any other reference. I don't really want to go to the trouble unless I can be sure this is the problem, but for 40 bucks I may take the chance.
    Thanks for doing all of the leg work for the rest of us.

    That caption was from a pic that I stole from the LS2 GTO guys. I tested it once I got it off. Resistance across the 2 terminals was infinate (open circuit). There really is no room to test it on car.

    Perhaps the info can point the dealership in the right direction.
