Hi
Apologies for repeating this, but inside the sender (at least on the ones I have seen) one end of the resistance wire is connected to the mazak body by trapping it under the insulated sleeve that goes round the 'live' connection to the terminal for the gauge. As resistance wire and mazak are dissimilar metals, a poor contact can result after decades. Dismantling, cleaning and reassembly should do the trick.
