DRIVERS SIDE GAS TANK IS LEAKING WITH STRONG GAS FUMES COMING FROM UNDER CAR SITTING STILL. LEAK IS AT THE BOTTOM SENDING UNIT ON THE LEFT PLASTIC TANK UNDER THE PASSENGER SEAT BEHIND THE DRIVER. I ISOLATED THE LEAK TO WHERE THE WIRES PLUG TO THE TANK GAUGE SENDING UNIT. THIS IS OBVIOUSLY A VERY DANGEROUS CONDITION THAT SHOULD NOT OCCUR EVER IN NORMAL OPERATING OF THE CAR. THIS CAR HAS NOT BEEN ABUSED OR WRECKED THAT I KNOW ABOUT SO, IT IS A MANUFACTURER DEFECT. IN ADDITION, RECENTLY, THERE WAS A MAJOR GASOLINE LEAK FROM A RUSTED LINE ON THE RIGHT TANK HIGH PRESSURE LINE GOING FROM THE FUEL PUMP TO THE ENGINE, WITH FUEL SPRAYING EVERYWHERE UNDER THE CAR. THIS WAS CAUSED BY A RUSTED LINE, PROBABLY FROM SALT ON WINTER ROADS. THE METAL FUEL LINE WAS VERY FLIMSY AND A HOLE HAD RUSTED IN IT. MERCEDES CLAIMS TO SELL A QUALITY AUTOMOBILE. MERCEDES SHOULD BE REQUIRED TO REPAIR SUCH OBVIOUSLY DANGEROUS DEFECTS FREE OF CHARGE TO THE CONSUMER. *TR
