On my '71 Jimmy, the PO let the tan wire contact the exhaust pipe and it burned out long ago. Since it's a major production to first drop the trailer hitch, then the 1/4'' steel armor plate around the fuel tank, til I can get to the tank straps and then, drop it -- I haven't done it yet. Replacing the Tan [or Lt Brn] wire is the easy part.
As a work-around, I have a clipboard in the cab where I log my miles, gas gallons bought, date, octane, price and many other details. That way I can 'cypher' my MPG vs. fuel onboard, and calculate what my gas level is [or should be]. Not the most practical solution, I'll admit. Fixing the wire or in-tank sender, would be better. Having a working accurate fuel gauge makes it a no-brainer. But I can carry a pretty accurate picture in my head of fuel usage, with the clipboard, and I'm used to it. When in doubt just add 10 gallons every 100 miles.
