Condition, Vehicles, Involved Dealer Action Information
CONDITION
General Motors has determined that a defect which relates to motor vehicle safety exists in some 1987 Oldsmobile Firenza models equipped with 2.0L
(RPO LT2, VIN Code K) engines. The fuel feed and/or return hose/pipe assemblies could crack or separate, allowing fuel to leak into the underhood
area. This condition could ultimately result in an underhood fire without prior warning. Such a fire could, in time, spread to the passenger compartment
and cause injury to any remaining occupants.

SERVICE PROCEDURE
1.
CAUTION: To reduce the risk of fire and personal injury, it is necessary to relieve fuel system pressure before servicing fuel system components.
Have a dry chemical (Class B) fire extinguisher near work area. To relieve the fuel system pressure, do the following:
Remove "Fuel Pump" fuse from fuse block in passenger compartment.
Crank engine - engine will start and run until fuel supply remaining in fuel lines has been consumed. Engage starter for 3.0 seconds to assure relief of any
remaining pressure.
Unless this procedure is followed before servicing fuel lines or connections, fuel spray could occur.

Use a backup wrench when loosening the screw coupling fittings at the fuel line ends.
