2007 BMW F800 ST Electrical System Problems

THE PLASTIC MOUNTING PLATE HOLDING THE FUEL PUMP AND FUEL GAUGE SENDING UNIT DEVELOPED A HAIRLINE CRACK. THIS CRACK ALLOWED FUEL TO ESCAPE FROM THE TANK UNCONTROLLED, WHICH COULD CAUSE A FIRE. THE MOTORCYCLE WAS PARKED IN THE GARAGE, WHERE A GAS WATER HEATER NEARBY COULD HAVE IGNITED THE FUMES. THIS CRACK WAS NOT CAUSED BY ANY CONTACT OR PRESSURE FROM ANY OTHER COMPONENT OF THE MOTORCYCLE AS IT IS PROTECTED BENEATH THE SEAT AND A SUBSTANTIAL RECESS IN THE FUEL TANK. THE LOCAL DEALERSHIP ADMITTED THAT THEY REPLACE AS MANY AS TWO OF THESE CRACKED MOUNTING PLATES PER MONTH. THIS CONDITION WAS NOT FOUND ON ANY RECALL NOTIFICATION THAT WE ARE AWARE OF. UNFORTUNATELY, THIS MOUNTING PLATE IS NOT AVAILABLE SEPARATELY, AS IT IS A COMPONENT ASSEMBLY OF THE FUEL PUMP AND SENDING UNIT, COSTING NEARLY $1000 TO REPLACE. *TR
