Heavy gas smell.....
 

I drove home from work last night (about 4 miles) and when I pulled my '97 (45k miles) in the garage, I noticed a heavy gas smell when I stopped. I thought maybe it was from the mower gas can and didn't think too much of it. This morning I drove into work and I smelled it again in the parking garage. Suddenly I am worried.

Any thoughts on what would cause this? :confused:
