FUEL PUMP COUPLER

NHTSA #08V180000 · Fuel System, Gasoline — Delivery — Fuel Pump · NHTSA notice

Reported April 23, 2008 · YAMAHA MOTOR CORPORATION, USA

Potentially affected: 9,600 vehicles

Yamaha campaign M2008-002R · Owners notified May 9, 2008 · Vehicles built July 1, 2004 – April 30, 2007 (per NHTSA) · Recall influenced by NHTSA's Office of Defects Investigation

Defect description

YAMAHA IS RECALLING 9,600 MY 2006-2007 CP250 AND MY 2005-2007 YP400 MOTORCYCLES. THE ENGINE COULD STALL AND BE DIFFICULT TO RESTART BECAUSE THE WIRE TERMINALS IN THE FUEL PUMP WIRE COUPLER HAVE CORRODED. WATER CAN ENTER FROM THE MAIN WIRE HARNESS END AND RUN THROUGH THE HARNESS TO THE FUEL PUMP COUPLER.

Safety consequence

IF THE WATER REMAINS IN THE COUPLER FOR AN EXTENDED PERIOD OF TIME, THE TERMINALS CAN BECOME CORRODED, WHICH CAN PREVENT THE FUEL PUMP FROM OPERATING PROPERLY. IF THIS CORROSION AFFECTS FUEL PUMP OPERATION WHILE THE SCOOTER IS BEING RIDDEN, THERE COULD BE A CRASH RESULTING IN INJURY OR DEATH.

Manufacturer remedy

DEALERS WILL INSTALL A SUB-HARNESS WHICH IS DESIGNED TO ALLOW ANY WATER BETWEEN THE WIRE HARNESS AND THE FUEL PUMP TO DRAIN OUT BEFORE IT REACHES THE FUEL PUMP. THE DEALER WILL ALSO INSPECT THE CONNECTORS. IF EITHER THE MAIN WIRE HARNESS CONNECTOR OR THE FUEL PUMP CONNECTORS IS ALREADY CORRODED, THE CORRESPONDING ASSEMBLY(IES) WILL ALSO BE REPLACED. THE RECALL BEGAN ON MAY 9, 2008. OWNERS MAY CONTACT YAMAHA AT 1-800-962-7926.
