Gasoline Smell when I turn heat on for first 60 seconds

Hello fellow Enthusiasts.

When I turn my car on and then put the heat on, I get a gasoline smell coming through the vents for the first minute or so. Any ideas what could cause this?

Thank you

Probably check to see if the N80 valve is functioning properly and that there are no air leaks in the area.

Ill have to figure out where that lives now, but thank you for the place to look!
