5. Remove the sending unit from the auxiliary tank. Remove the Diesel Fuel Strainer from

the pick-up tube. With a vacuum gauge (which can be purchased from any automotive

2. Check all Chassis grounds are good

3. Make sure the yellow wire is to the center post of the auxiliary tank sending unit and it is

not touching ground.

A. If the auxiliary tank sending unit is good—replace the auxiliary fuel gauge

B. If the auxiliary tank sending unit is bad—replace the resistor float of the sending unit.

Note: When checking Ohm value, move the float arm up and down slowly. If there are dead spots
