Every time I turn my van off, I smell gas outside the car. What is wrong? on 2005 Dodge Caravan

This only happens when I have been driving the car and I only smell it outside the car. Nothing, that I can see, is leaking from the car, and I never smell the gas inside of the car. I will be able to smell gas like 30 minutes to an hour after I turn the car off. What could this possibly be?

1st have your gas cap tested, the pressure in the tank could be letting vabors escape thru your cap. for like $8 just replace it and see if that fixes the problem
