temperature sender question

Yep, I think so, but nothing is ever that easy, but what about the dash gauge, if it’s electric the ohms have to match wouldn’t they?
(Matching ohms are really hard to find, kind of like smart hockey goalies)
I think there are many threads about this; did you have any luck trying various search headings?

i know for a fact that if your system was 6 volt then get a 6 volt sending unit. i had a 55 f100, 6 volt positive ground, converted it to 12 volts and bought a 12 volt sending unit and installed it, no way did it read right. i was at a wrecking yard and saw a old v8 Flathead and pulled the sending unit out of it, my gauge worked great after that. a shop told me that the gauges didnt know the difference. id check with some of the old timers that are familiar with this to make sure but i know what i was told and what worked for me.

Temp sender.
Hotrod has it right. The sender and gauge are a matched set. Voltage, polarity and ohms resistance. Not just min and max ohms, but the linear curve, or you get false readings. Mixing and matching is nearly impossible.
Get a sending unit that matches the gauge (ie, original for the vehicle and engine that came in it.) The sender doesn't care what engine it is in. It just translates heat into ohms resistance. When you switch to 12v, get a reducer to keep the dash gauge at 6v.

All you need is a 6v regulator that bolts to the back of the gauge and can use original gauge and sending unit. You buy one regulator for each gauge so that makes a total of three, water, oil and gas. I did this on a 51 panel and kept the original gauges and mounted the flathead sending units into brass adpaters onto the late model engine. Works great.
