What I did was to remove the sending unit from the tank. Put a voltage meter on the output lead and check to see that different voltages occur at different float levels (extreme high/low).

If that occurs, reconnect everything and recheck at the incoming lead to the ivr. (sending unit still out of tank). If you get different readings there, then reconnect to the gauge. The gauge should register a different reading when the sending unit float is at different points, still out of tank.

I did end up having to bend and alter the sending unit float position to get the readings I wanted (above full when full and below empty when truly empty).
