My fuel gauge has never worked on my 1975 IH 766. I refuel after every use, like it or not. I have never run it empty by doing this
Grew up running old stuff that didn't have gauges.
Filling up was right after checking the oil and driving to the pump.
Away from home filling was first, from cans.
Never ran out.
Now the dam Jeep I had?
Gauge didn't work, so I used mileage.
I didn't notice when the tank started to leak.
That was a long walk!
