46 Hudson fuel gauge ohms reading

Bitburger

Can someone please tell me what the ohms data for a fuel gauge/ sending unit on a 46 Hudson is?

I've read on one of these threads that stepdown fuel gauges/sending units read: 0 ohms full and 100 ohms empty. I would have guessed O empty and 100 full.

Are 46/47 models the same or a different ohms value?

I find no data on this in my manual.

Same as Stepdown: @10 Ohms full, 75-80 Ohms empty is in the ballpark.

My understanding is that both dash and tank units are bi-metal, not rheostat.

The company I purchased my tank from asked the ohms rating in order to match a modern sending unit to the original Hudson fuel gauge. Bi-metal vs rheostat was not discussed.
