fuel leak

yes mrnickleye is right. I had the same problem several years ago and it was because the canister was plugged. I ended up getting one from a junkyard cause the dealer here didn't have any. They considered it a non moving item and no one changes it anyways till I showed up asking about it.
The evap system is supposed to prevent fuel vapors from entering the atmosphere, by routing the vapors through the cannister to the intake manifold then on to the combustion chamber. If the smell is coming from the engine bay then the canister is plugged or one of the lines came off. The system is why the gas cap is sealed. On older cars you will notice the release of pressure from the cap when you fill up on a hot day while going on a trip.

Thanks for the info. I will check out the cannister tomorrow and check for some lines that could be loose. With our cars, the evap. system takes away that pressure that builds up from the cap? Is that right?
When I drive for a bit and then fill up, there is a lot of pressure being released from the gas cap. Normal?
