I did a lot of gas gage work when I worked nine years for a car collector with some 400 cars.
A late ‘36 had an electric fuel gage wheras early ‘36 had the same hydrostatic gage as the ‘35. We never tried to make the hydrostic gages work.
The late ‘36 electric gages bolt right in the ‘36 so I put electric 36 units in all of out ‘35 and early 36 cars. We only had 6 volt cars but C&G has everything you need to put in 12 volt gages or convert the 6 volt stuf to work on 12.
For non Ford cars I ordered gages and tank units for 6 volt Jeeps.
I have bought a set when my local NAPA was still in business. It consisted of a round gage, a tank unit and the ring you have the radiator shop solder to the tank to fit the tank unit to.
I did that when I converted my F1 over to 12 volts. Always accurate.
On my 12 volt Nash I used a Chev sending unit and got a round gage from o’reilys for a Chev. It’s worked fine for 23 years.
