    It's here in the forum, I know it's been discussed before but I don't have time to look it up for you.

    From what I read.. 70 to 10 ohms. That being said, I am having trouble with mine. I put resitors in series with the sensor wire (no sending unit) and 1 ohm would make the guage read full and around 6 would read near empty. Been scratchin' my head over this one for a while...
