P0440 code

Found the culprit to be rust/cracks in the flange between the filler neck plastic insert and the pipe itself. RTV spread all around the outside of the filler neck and 15 minutes into my next drive the light extinguished

I like it...

I just got the code too, and a whiff of gas on fill-ups (nightly).
