Resistance of fuel sending unit case 580d

I?m working to build a replacement gauge cluster for my case 580D. My stumbling block right now is the fuel sending unit. Does anyone know what the resistance might be, so I can figure out a match for a gauge. That info doesn?t seem to be available in the schematic.

Thanks, Cole

Lacking shop manual info., you may have to remove it and MEASURE the resistance, flow "UP" and float "DOWN".

Could be done by filling the tank, then emptying it, as well.
 
Ohm meter lead to sender terminal and other lead to sender unit ground. Coat hanger, reach into tank and push down/lift up on actuating arm read out full travel in nominal ohms.

Case 580D fuel sender Case p/n D83480 sub to 9809196.
