NHTSA Complaint #10417320 — 2008 BMW R 1200 GS

A PLASTIC FLANGE ON THE FUEL PUMP CRACKED ALLOWING FUEL TO LEAK. THE FLANGE CONTAINS AN INTERNAL THREAD THAT SECURES ONE OF THE FUEL LINES. SEVERAL CRACKS ARE VISIBLE AROUND THE CIRCUMFERENCE OF THE FLANGE. CRACKS, IN MY OPINION, APPEAR TO BE RELATED TO OVER-TORQUE AT ASSEMBLY AND/OR MATERIAL DEGRADATION DUE TO THE COMBINED EFFECTS OF EXPOSURE TO FUEL, TIME AND AMBIENT TEMPERATURE. THE FUEL PUMP IS LOCATED IN THE FUEL TANK THAT IS POSITIONED DIRECTLY ABOVE THE ENGINE AND EXHAUST PIPE. FORTUNATELY THE VOLUME OF LEAKED FUEL WAS SMALL (<1 FL OZ) AND WAS CONTAINED WITHIN A DEPRESSED CAVITY ON THE TOP OF THE PUMP, OTHERWISE IT COULD HAVE DRIPPED ONTO THE HOT ENGINE AND EXHAUST HEADER POSSIBLY CAUSING A FIRE.
