I searched for "+fuel +gauge +ohms" and found a few threads stating 0-90 ohms, but also http://www.914world.com/bbs2/index.php?showtopic=44848 where James Montebello (RIP ) states it's 5-75 ohms. I trust James a WHOLE LOT!

A 0-90 ohm gauge probably wont read exactly right. It will probably not show all the way full and the tank will be empty before gauge shows it. Pull your sender out and measure as you move the float. James Montebello in the thread that McMark posted says these readings may be +/- 10 ohms.

Hope this helps,
