Strong smell of gasoline evident on driver's side rear when stationary or even not running and parked . Research online with the search criteria of "gasoline smell on driver side rear" produced numerous complaints and questions on this phenomenon. The culprit is the fuel pumps/filters/seals for the two gasoline tanks. They are make from plastic and are prone to cracks or leaks from full tanks. One Porsche parts supplier put it this way on their diy repair page "the question is not if, but when you experience this problem. " the solution is to take out the rear seats, cut the carpet, remove the seat belt anchors, remove the cover under the carpet to access the pumps and filter. This is a problem Porsche must know about as they have changed the design of the pump parts.
