New Guy... 96 Cobra???

Fuel tank filler grommet?

It's very hard to diagnose without more info via the interwebs. Does it do it on turns, under hard acceleration or just all the time?

I'd say its the grommet. I wouldn't continue to drive with gas leaking on hot exhaust parts. Just my own personal "I don't want to burn to death in my car" preference.

It's a cheap part. Sucks to replace. Run your fuel down to 1/4 or below before you drop the tank. Use lube of some sort to help reinstall the grommet as they can be snug (I mean really, who wants to throw a hot dog down a hallway?).

Good luck but I'd say you've found your culprit.
