Yep. That is under a dollar per Ohm

Sender Unit Adjustment Possible?

.4 to about 60 ohms full to empty with output voltage to the sender going from 8 to about 5 volts from full to empty.
Adding a 2 ohm resistor to the sender with simulating a full tank, output dropped the gas gauge needle about 1/16th of an inch. I did not measure the voltage beyond the resistor to see how much that dropped. If non-linear, at full it drops 1/16th but at 1/4 tank, who knows.
So now we know we can play with the gauge this way. If I was super anal, I would have generated a voltage and ohm to gauge position graph so I could see how adding 2 ohms would affect the gauge at each point.
Respectfully, Bavbob the science guy.
