Dealer Campaign, Owner Change, Parts & Technician Procedure Information
DEALER CAMPAIGN RESPONSIBILITYDealers are to service all vehicles subject to this campaign 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 vehicle inventory, or it is in your dealership for service in the future, you should take the steps necessary to be sure the campaign correction has been made before reselling or releasing the vehicle.
Owners of vehicles recently sold from your new vehicle inventory are to be contacted by the dealer, and arrangements made to make the required correction according to instructions contained in this bulletin.
CHANGE OF OWNER INFORMATION
Dealers are to use the Dealer Communication System (DCS) to provide Buick Motor Division with subsequent Buick owner information. By reporting a change of owner name or address of a vehicle in campaign status over the DCS, the need to send a CVAR form for that vehicle is eliminated. Terminal input instructions are covered in the DCS Manual under Section 9, Page 9-J01A and B.
PARTS INFORMATION
Parts required to complete this campaign are to be obtained from General Motors Service Parts Operations (GMSPO). To ensure these parts will be obtained as soon as possible, they should be ordered from GMSPO on a "C.I.O." order with NO special instruction code, but on an advise code (2).

FIGURE 2:
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 end of hose opposite 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, beginning with Step 4.
If date code is not 04/28/87, hose replacement is NOT required. Reinstall convoluted sleeve and proceed directly to Step 10.
Hose Replacement
4. Disconnect negative battery cable and remove fuel tank filler cap.
5. Relieve pressure in fuel system following instructions below:
CAUTION: To reduce the risk of fire and personal injury, it is necessary to relieve the fuel system pressure before servicing fuel system components. Unless this procedure is followed before servicing fuel lines or connections, fuel spray could occur.
A. Connect fuel gage J 34730-1 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 an 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.
7. Replace O-Ring seal on engine and chassis fuel feed pipe making sure O-Rings are in proper position. Connect new fuel feed hose, Part Number 10052161, to engine and chassis fuel feed pipes ensuring hose is not kinked or twisted. Torque hose fittings to 20-34 N-m (15-25 ft.lbs.) utilizing a backup wrench on fittings.
