Fuel tank sizes?

Even if you had one wire still intact, the voltage is low enough that one strand of wire would still provide an adequate signal.

I just changed my fuel level sender in my 1987 turbo and saw no evidence of "frayed" wiring.
It was the potentiometer resistance sweep (common problem for any type of (non-sealed?) potentiometer) to degrade this way.

take a pill...

when the wires are worn the resistance gets thrown off giving a less accurate signal at the lower fuel level range where the most wear generally is. eventually the wires break and the gauge reads zero before the tank is actually empty, i figured you could gather what i was getting at. i have seen a number of 2nd gens with frayed wires below 1/4 tank which worked fine up until that point then dropped to 0 on the gauge as soon as they hit the bad spot.
