I added fuel to one of my tanks in 1 quart increments to characterize the response of the sender to the fuel level in the tank. Initially the sender did not respond and then began to respond erratically. Apparently adding 1 qt of fuel is not enough to overcome the friction in the sender. After the tank was about half full I could tap the sender housing after adding each quart and it would respond. Here's the result:

At 24.5 gallons there was 92.6 ohms resistance in the sender.

From 1/2 full to full the response appears nearly linear. Somewhere between empty and 1/2 full there has to be a bend in the curve. Has anyone done this before and published the results?
