Condition

Some owners may comment that the fuel gauge indicates empty after only going 200 to 250 miles, and they are only able to put approximately 23 gallons or less of fuel in the 30 gallon tank.

Cause





The Fuel Level Indication System was designed with excessive empty reserve. The Fuel Level Sender will be labeled with Broadcast code "TCB", (see Figure 1). Vehicles built after December 14, 1996, have the revised Float Arm Assembly.

Correction





Following the procedure described in Section 8A of the Service Manual, remove the Sender Assembly and replace the original Float and Arm with P/N 25312833 (see Figure 2). Reinstall the Sender Assembly and Tank.
