Car has port injection, and a fuel system. Shop checked over both and there are no fuel leaks. The smell was not present when I took to shop so was hard to trace down.

getting an intermittent raw fuel smell (e85) recently after a full tank fill up when parked, fuel system has been on for a couple months but only started Smelling this last week after a full tank. My current suspect is the fuel tank vent as the smell is very strong around the left side wheel well and near firewall. Has anybody experienced this?

Iā€™m no expert but isnā€™t there a charcoal filter on the fuel tank vent to deal with vapor? Could the tank perhaps have been overfilled causing the filter to be saturated in fuel?

Update: I was looking around and found a nice video that could describe a scenario why this might be happening.

I have this same issue but only when I overfill. Mainly due to mixing ethanol lol.
