2002 Saturn L200 Gasoline Smells

When we drive into our garage a gasoline smell invades the area. We do not see any gasoline on the floor of the garage. We have only had a very minor reduction in gasoline performance.

The smell is so bad it invades a portion of our house.

Any idea how to fiix this? A new gasoline filter? replace the rubber gas lines?

Please advise. Thanks

Mark
