Sorry for reopening an old post. The wife's 2001 coupe has the same issue as the OP, real strong fuel smell. Driving home last night had someone pull up yelling about there is fuel coming out from under the bumper. Car has popped two codes PO455 & PO457, I replaced the gas cap and no change. Looked under car tonight to see the gasket as seen in the image. Turned the car on to see any leaking and the only leaking was directly out of the exhaust....not on top, inside the pipe? I'm going to replace the fuel filler tube gasket on tuesday when it comes in but if there is indeed fuel coming out of exhaust this concerns me. Anyone have any thought on this? Thanks in advance.
