Is there a way to bench test the fuel gauge?

[TIGGER]

The gas gauge on our 91 Explorer hasn't worked for over a year now and the wife wants it fixed. I ground out the yellow wire and the gauge did not peg so I assume it is the gauge or a wiring problem. Is there a way to check the gauge on the bench if I pull it from the cluster?

It may be the anti-slosh module too. Here's the wiring diagram for it.

Is the anti slosh module the circuit board on the side of the instrument cluster?

To test gauge and float unit without tearing anything apart try these instructions:

find the wire going to the fuel guage with the key on, a pulsing voltage to it usually about 8 volts pulsing and touch it to ground if the guage goes to full the guage is working the sender controls the ground goin to the guage.

I went to the wrecking yard and got a slosh module from another rig. I installed it and the fuel gauge is working again I made sure to grab one from a rig that did not have the needle pegged on empty.

thanks for the help guys
