FUEL LEVEL SPECIFICATIONS

The information in this table is intended for use with the J 33431-C Signal Generator and
Instrument Panel Tester. The fuel level sensor values represent the test values to be used on the
Signal Generator to drive the fuel gage display to the indicated positions. Vehicles that require
more than one fuel level sensor calculate gage position from many possible resistance
combinations of fuel levels between the two tanks. Therefore, the values in the table may not
correlate directly to readings taken from the vehicle primary or secondary sending units.

The values in this table are approximate values based on information obtained from properly
operating vehicles. Actual results may vary slightly.
