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.

I had the exact same problem on my sender when I was using the stock dash.

When I changed out the dash and built my own using all aftermkt gauges I first tried the autometer generic replacement sender = SHIT
Then I tried the marine Tempo sender = less shit, but still shit.
Then I bought a new Mazda sender and a programable autometer gauge = awesome.
Then I built my own tank and went with a WEMA and the same Autometer programable sender = awesomeness

If you need to replace the sender, which I suspect is highly likely, as Ted said, non sealed units as they are, you can actually see corrosion on the sweep giving inaccurate signals, I have yet to find a better sender than the Mazda units. Aftermkt wise, WEMA is the way to go.
