Fuel smell in cab & outside

ok here goes.

I fill up the tank with gas. Drive it down the road. After a few miles I smell gas in the cab. I get home, and get out. I can smell gas outside too. The smell dissapears after awile.

I cant see a fuel leak anywhere. Does anyone know where it might be leaking? I am not familiar with these engines.

thanks,
Philllip


ON EDIT:

Whoa, I thought my sig. was filled out. The car is a 1996 Honda Civic 2door. EX I think. Its got a little 4 banger. 5 speed tranny.
