DEFECT INVOLVED

A FITTING MAY LOOSEN ENOUGH TO LEAK FUEL INTO THE UNDERHOOD AREA, AND IF AN IGNITION SOURCE IS PRESENT, COULD RESULT IN A FIRE.

VEHICLES INVOLVED

INVOLVED ARE ALL 1990 BUICK SKYLARKS WITHIN THE FOLLOWING VIN RANGE:

MODEL YEAR PLANT FROM THROUGH

1990 LANSING LM042960 LM044072

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
