I was able to get my modern sender to give an accurate gauge reading near empty tank. Gauge remains very inaccurate in the upper range. Fed the sender wire thru a 9-ohm resistor just ahead of the sender. Required trial-and-error to settle on the 9 ohm. (driving till emty with a gas can in the trunk) I suspect every sender, with different float arm adjustments, would be a little different.
