Default Fuel Sending unit empty / full OHM values needed.

I could not find Series I fuel tanks so I bought a pair of Series II tanks and swapped the fittings.
I also bought new Series II sending units for the tanks.
My fuel gauges do not work now.
Does anyone know what the empty / full ohm readings are for the Series II sending units?
I have been trying to run dry one of the tanks but now it appears that my fuel switching valve is drawing from both tanks at any given time.
Yet another gremlin to chase down and destroy...

Have you tried the JTIS for more information? Also, since you have your ohmmeter out, check the circuit for continuity and see if you have a good connection to earth (ground).
