Smell of gas near rear wheel well after shutting down engine

[Masospaghetti]

I've noticed the smell of gasoline after shutting down the engine near the rear wheel wells, specifically the driver's side. I have it up on jacks now with the protective covers off (fuel filter, evap canister, and expansion tank exposed) and I couldn't smell anything from any of the visible connections. I also checked the fuel pump seal and can't smell anything there. I only smell it when the motor is shut off. This fuel/evap system is very complicated compared to what I am used to!


I haven't pulled the driver wheel well liner yet but I know there's a few evap components behind there too.


Any suggestions what it might be? 2003 3.0i with 163000 miles. Thx!!!
