VEHICLES WITH GASOLINE ENGINES AND DUAL FUEL TANKS MAY EXPERIENCE THE TRANSFER OF FUEL FROM ONE TANK TO THE OTHER THROUGH A MALFUNCTIONING CHECK VALVE WITHIN THE FUEL PUMP ASSEMBLY. THIS COULD CAUSE THE CAPACITY OF THE OTHER TANK TO BE EXCEEDED, RESULTING IN FUEL OVERFLOW PAST THE FILLER CAP. IN THE PRESENCE OF AN IGNITION SOURCE, A FIRE COULD RESULT. CORRECTION: FUEL PRESSURE REGULATOR WILL BE REPLACED AND REDUNDANT CHECK VALVES WILL BE INSTALLED ON AFFECTED VEHICLES.
