What would cause a fairly strong gas smell on the drivers side of the car? It's a 98 GT and it gets worse when driving but can smell it a little bit after it's been sitting. It doesn't seem to be losing any gas but if it is it's insanely slow. After driving for about a half hour one time I got home and popped the hood and couldn't smell any gas. I also can't smell it from the back of the car and whenever I have a passenger they can't smell it on their side.
