The fuel feed hose could leak at the coupling on the engine end of the hose assembly. This condition could allow fuel to leak into the engine compartment and an engine compartment fire may result without prior warning. Such a fire could, in time, spread to the passenger compartment.
VEHICLES INVOLVED

Plant Beginning Through and Including ----- ---------- --------------------- Oshawa#l J9323208 J9338563
Ste. Therese J2305145 J2307305
NOTICE: It is estimated that only 12% of the vehicles to be inspected will require fuel feed hose assembly replacement. Do not inspect vehicles having engines other than VIN Code W.
DEALER ACTION
To prevent this condition from occurring, the fuel feed hose assembly must be inspected, and if necessary, replaced with a new hose assembly according to instructions contained in the SERVICE PROCEDURE section of this bulletin.
Dealers are to perform this campaign on all involved vehicles at no charge to owners, regardless of mileage, age of vehicle, or ownership from this time forward.
Whenever a vehicle subject to this campaign is taken into your new or used car inventory, or it is in your dealership for service, you are to ensure the campaign correction has been made before selling or releasing the vehicle.
Dealers are to contact owners of vehicles recently sold from your new vehicle inventory and arrange for the campaign correction to be performed.
SERVICE PROCEDURE
1. Open and support hood.
2. Identify fuel feed hose (Figure 1) and carefully slip protective convoluted sleeve partially off hose assembly exposing identification codes (Figure 2). It is recommended that sleeve removal be initiated at the end of the hose opposite the sleeve retaining clip.
3. By inspecting hose date code (Figure 2) determine if hose was produced on suspect date ( 04 28 87 ).
NOTICE: To aid in hose date code identification, use of a mirror may be required. DO NOT TWIST HOSE TO INSPECT DATE CODE.
If date code is 04/28/87, replace hose assembly according to Hose Replacement instructions below.
If date code is not 04/28/ 87, hose replacement is NOT required. Reinstall convoluted sleeve and proceed directly to Step 10.

A. Connect fuel gage J 34430-1 or equivalent to fuel pressure connection. Wrap a shop cloth around fitting while connecting gage to collect fuel. Then place cloth in an approved container.
B. Install bleed hose into the approved container and open valve to bleed system pressure.
6. Disconnect fuel feed hose at engine and chassis fuel feed pipes utilizing a backup wrench on fittings.

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.
