First thing that comes to mind is the fuel vapor canister and purge solenoid. I had a solenoid go bad and give the same strong fuel odor presence. The solenoid is under the plenum.When the fuel got warmed up from circulating to the hot engine, the vapors increased to the point I could smell a considerable amount of fuel in the interior. That was thanks to the solenoid being seized and not allowing the engine to pull the vapors into the plenum to burn.

If your car was idling for a bit and the engine got up to temp, that could be the issue.
