They want $166 for the entire fuel module, all you want is the gauge sender. That should be about $60.

The float in the tank is connected to a potentiometer.

As the float raises and lowers, the resistance changes.

You can check the resistance of the wires going to the gauge; if it's in the ~40-200 ohm range then the sender is fine, if not then you have a sender problem.

If one of the sender wires is grounded someplace, then that would be your problem. I lost my fuel gauge when I ran a steel-braided fuel line from my tank to the sender.

First gens work like that, anyways.
