Service Procedure

1. Place the vehicle on a hoist and disconnect negative battery cable.

2. Raise vehicle, observing the instructions and cautions listed in the applicable 1989 Pontiac Sunbird Service Manual (Section 0A) regarding hoisting of the vehicle.

3. Using Figures 1 and 2, find the precise area on the bottom of the fuel tank to be inspected. The view in Figure 1 is looking up at the bottom of the fuel tank (bottom of the Figure is toward the vehicle front end). Any waviness of sheet metal OUTSIDE the dashed line box is acceptable.

It is expected that only one of every six fuel tanks inspected will be deformed as shown in Figures 1. Other areas of the tank surface may have some waviness which does not affect tank,life.

If the deformation ("raised area") is found at the exact location shown in the Figures, proceed to Step 4; otherwise to Step 6.

4. If the vehicle has a 2.OL engine (VIN Codes K or M), obtain a Fuel Tank part number 22527083 to replace the tank on the vehicle.

Also, obtain a fuel sender O-Ring and sound insulators, as listed in the PARTS INFORMATION section.


5 . Replace the fuel tank, observing the instructions and CAUTIONS as listed in the 1989 Pontiac Sunbird Service Manual, Section 6-C.

6. Lower vehicle, reconnect negative battery cable, and install a Campaign Identification Label.
