CAR IS A SUBARU OUTBACK 2001. COMPLAINT IS STRONG FUEL SMELL AND VAPORS IN THE CAR CABIN WHEN OUTSIDE AIR TEMPERATURE FALLS BELOW 30 DEGREES OR SO. SMELL PERMEATES OUR CLOTHING TO THE EXTENT THAT WHEN WE LEAVE THE CAR AND ENCOUNTER PEOPLE, THEY COMMENT THAT WE SMELL LIKE GASOLINE. FUEL LINES HAVE BEEN CHECKED AS HAVE CLAMPS AND HOSES. NO RESOLUTION. WE MUST DRIVE BREATHING STRONG FUMES. OPENING WINDOWS DISSIPATES FUMES SOMEWHAT, BUT NOT COMPLETELY. PROBLEM IS WORSE WITH HEATER RUNNING, SO WE TURN IT OFF. ADDITIONAL CONCERN IS THAT WHEN DRIVING WITHOUT HEAT, THE FRONT WINDSHIELD DEFROSTER IS NOT OPERATIONAL, RESULTING IN THE WINDSHIELD BEING ICED OVER AND/OR COVERED WITH CONDENSATION. THIS CAUSES VISUAL IMPAIRMENT AND IS A DRIVING HAZARD. *TR
