### Condition

Some customers may comment about inaccurate or erratic fuel gauge readings. A typical comment might be that it appears from the gauge reading that there is fuel available, yet the tank is nearly empty.

### Cause

This condition may be the result of the corrosive effect of certain fuel blends on the contact surfaces of the fuel tank sender.

### Correction

Important:

• | When servicing the fuel tank module or the fuel sender, DO NOT replace both parts. Only replace the appropriate part to repair the customer's concern.

• | The complete fuel level sender assembly P/N 22683260 is no longer available through GMSPO. This assembly is now serviced by a fuel tank module P/N 88957239 (minus sender) and the fuel tank sender, P/N 22709333. These two parts are no longer sold as one unit and can only be purchased separately.

• | Dealers within the provinces of British Columbia, Quebec, New Brunswick and the State of Maine, should refer to Customer Satisfaction Campaign 00101, dated January , 2001.

When fuel gauge diagnosis in the Service Manual indicates the cause to be the fuel tank sender, replace the existing sender with a new sender, P/N 22709333, with improved corrosion resistant wiper contacts.

Important: With the availability of this new fuel level sender kit, DO NOT replace the complete fuel level sender assembly, P/N 22683260.

To insure correct installation, follow the instructions contained in the kit and the service procedure in the applicable Service Manual.
