CAMPAIGN: FRONT FUEL FEED AND RETURN HOSES MAY LEAK FUEL

Models: 1990 SKYLARK AND CUTLASS CALAIS

NOTICE: ALL GM DEALERS WERE ADVISED OF THIS PRODUCT CAMPAIGN BY DCS MESSAGE ON APRIL 19, 1990

General Motors of Canada has determined that a defect which relates to motor vehicle safety exists in some 1990 Buick Skylark and Olds Cutlass Calais model vehicles. Some of these vehicles may have improperly torqued connections of the Front Fuel Feed/Return Hoses to the Fuel Pipes at the body rail. A fitting may loosen enough to leak fuel into the underhood area, and if an ignition source is present, could result in a fire.

To prevent this condition from occurring, dealers will torque the fittings of the Front Fuel Feed/Return Hoses at the body rail lines in the engine compartment on suspect vehicles per the Vehicles Involved and Service Procedure sections of this bulletin.
