I'm sure it's a gas leak. I went to fuel up the other day and almost couldn't pump gas. Messed with it for a few mins and got it take. When I opened up the gas cap it was wet from fuel but couldn't pump gas wtf? Is there some kind of valve at the fuel tank neck on a 2007 997.1 turbo? I'll reset code and it'll come back when ever it wants. Hoping to get more info before tearing things down. Thanks
