Gasoline Smell in Cabin

Every time I fill up the tank on my truck the inside cabin smells of gas. I got home and looked behind the seat but could not find any leaking gas. The gas smell is not as prominent when the tank is half full. I did replace the gas cap with a new one. That stopped that gas from running down the side of the truck.

Any ideas?

I’ll bet a punch in the gut that the spot where the filler neck goes into the tank has a real small leak. This is common, and preventable. When you gas up, notice that you are probably leaning on the pump handle…this puts too much of a load on the joint.

You can have the tank removed, steam cleaned, and repaired at many radiator shops, and I would assume for less than 50 bucks.
