So, one might ask, how would I go about calibrating the gauge as you did WITHOUT having a spare sender to play with.
The gauge registers full at 0.5 ohms, and empty at 90 ohms.
I would use a 45 ohm, and a 22 ohm resistor to check the gauge. You don’t have to disassemble the cockpit and remove the gauge. You can do it by snipping the leads on the fuel sender at the tank and substituting the resistors for the sender. Of course you will have to butt splice the wires back but no biggie. If you wanted to do it fancier you could use a 100 ohm potentiometer and your voltmeter to set whatever resistance you desire.
