Thanks, a ohmmeter measuring resistance with the different float levels should tell you if it is a linear leading and if so I don’t see why you can’t put a sweep gauge on it. Unless the fuel reading is tied to the computer causing a condition to stop the car when the fuel gets to low. You could check that by removing the wire from the float, outside the fuel tank, and see how the machines operates with it disconnected. Don’t let the loose end short out on anything while you try it.
