equus fuel gauge problem

Need gauge part number. Is the car the Demon in the pix?

Is this the stock fuel tank sender? If so, model 7381 is the PN you need to match that.

Equus makes at least 3 gauges and they work with different senders. 2 of them (7381 and 7383) work with high resistance for a low tank and a low resistance for a full tank but the model 7382 is backwards. So if if models it pegs past F all the time, then it sound like a short to ground on the wire to the tank or in the sender itself or you have a 7382 and need one of the others.

Do you have a voltmenter? If so, remove the wire to the sender and use the resistance function of the meter to measure the resistance (ohms) in the sender. If you need help in doing this, let us know.
