Fuel Tank Sending Unit 1936

[Mr. Will]

I found a NOS fuel tank sending unit FAA-9275-A that says its for 52-53 Ford passenger car 6-cylinder. I am trying to use it in my 36 but it doesn't read correctly. I thought that all the 6-volt units would be compatible with the 6-volt gauges?
Can anyone here shed some light on this subject. What will work and what will not. Any help would be appreciated.


Thanks Dan
