Have a 57 Monarch Richelieu with the 312, pretty much stock. The fuel sender is out of wack. What should the ohms measure out to? If I fiddle with it, I get about 15 ohms full to 95 ohms empty. Does anybody know the correct range?

When I fixed my 54 Meteor, I bought a fuel sending unit from Princess Auto and using a resistor I managed to get that one to work perfectly. I plan on doing the same with the Monarch, but cannot find the specs anywhere.

I see a listing on Rockauto for a 57 Ford Fairlane sending unit, but not for a Mercury. It visually looks the same, do they read differently?
