Sydney has a good point. What I would do at this point is clip-lead the sender to the car wiring and move the arm while observing the fuel gauge. If it operates the gauge, then you could check the calibration if you know the total travel for the float arm in the tank. If the wiper arm is adjustable you can adjust it while its out of the tank. The amount of float travel in your tank may only be the portion of the windings that are in the 10 to 70 ohm range.
