Gas coming out of fuel fill hole?
Yes, the little buggers love finding holes and filling them. Not so much here, but further west, they're rife and will fill aircraft tank vent tubes and pitots overnight if given an opportunity.
In the twilight zone, I assume you've got an early fuel tank with the little expansion tank on top. I couldn't imagine any possible way it could go wrong, very lightly pressurising the line leading from the first check valve to see if air gets to the line opposite, likewise the catch tank under the TB might be worth a shake to see if it's maybe blocked with charcoal bits. The charcoal canister itself has a rubber vent, but don't quite understand how that works.
Used to find the muffler side of the tank gets warmer than the rest when jacking it up after a session, but it's surprising how hot the tank gets generally - recirculating fuel in the engine bay (which might be an argument for a dead head fuel system), do you have a muffler heat shield in place?
Edit: Oops, same point raised above.

Well…I think it was the gas cap lol i don’t quite understand why or how, but I have driven 5-6 times with a new gas cap and have had zero issues. So if anyone else is having this problem I guess start there!
I had the evap purge solenoid in place but the wires were disconnected on my car for a while, and eventually I got tired of the fuel vapor smell. I reconnected the wires and configured the ECU to send it about 50-80% duty cycle in vacuum when the engine is cruising. Doing that has reduced the fuel smell nicely, although there does seem to be a little pressure in the fuel tank when I remove the cap it's better than it was with the solenoid disabled.
