Everytime I get my car filled up, and garage park it, I smell of gas

I do not top it off, and over time the smell is stronger and lasts longer

Check your fuel filler neck. It may have rusted and some fuel splashes through this small hole in the neck. Fumes from the tank will also escape through this gap..Do you have a check engine light on? Also check to make sure all hoses are attached and not cracked in this area.

Hey Buddy, I had that same issue for almost 6 months. Then my shop realized, it was the gasket underneath the back passenger seat on the right that needed to be replaced. I got that done & wow, no more smell :)
