What's the same no matter which tank is selected??? The fuel gauge and the sender wire from terminal B of the valve to the gauge.
Typical Fuel Sender Resistances were within ±3Ω or so on my test gauges from several different years: - E = 0-3Ω
- ¼= 26-32Ω
- ½= 42-48Ω
- ¾= 61-67Ω
- F = 87-93Ω
¾ is less resistance than F. The only way to get less resistance in this circuit is for the wire insulation to be rubbed through and make an intermittent ground connection. That's unlikely to be repeatable over time.
I'd say it's probably the gauge itself.

Right on Hatzie, I need to pull the dash apart to change my dash so, while I am in there, I will do some testing. thanks for the tolerances - as always, I appreciate your knowledge and guidance.
