Bench testing dash clusters ??
A "pot" or "potentiometer" get's it's name from "controlling potential". By accepted definition, a variable resistor "to be a pot" is three terminals........the two ends of the resistor, and the moving contact.
A pot can be used (as in this case) as a "rheostat" which is only a 2 terminal variable resistor
All you are doing, is sliding a contact along the resistor, until you reach whatever value you want
Here are some laboratory / demo pots. Nothing more than a resistor and a sliding contact
Here's a great big high wattage "pot" because it has three terminals. If it only had two, like your fuel sender (the terminal and ground) it would be a "rheostat"
