Help with gas smell
2020 Sti. Only mods are IAG AOS and catback Borla dual exhuast. No leaks in engine bay, gas cap present and was secured, no visible leaks underneath vehicle. Gas gauge is one-two ish tick below full.
Car was idling in parking lot for 30 mins AC on Low full blast for passengers. Inside cabin started smelling like fuel. Strong enough for windows to be rolled down.
Drove around and fuel smell dissipated even with it still on full blast. Next stop fuel could be smelled when exiting car on driver side. No fuel smells came back for the next few hours. Parked at home, when walking around the car a very strong gas smell can be noticed specifically near the driver side exhaust.
Need help narrowing down what might be the issue. Looking for a better idea that could be fixed before having to go to the dealership.
Don't want to risk it attempting to travel during the 4th weekend if its worse than it seems
