Hello good people,
My question is about the sending unit in the gas tank of my Chevy 1953 3100 1/2 ton. My gauge doesn't work and I am not sure about what to do first.
It's been converted to 12 volt.
How many ohm's does the sending unit need to be? and is there a difference in the 6 volts and 12 volt units in the tank? and can I test it by shorting the hot wire to the body to test it to see if the gauge on the dash works? Not sure here?

Always many thanks
