Using original gauges with newer engine

Using original gauges with newer engine
I am swapping a 351w into my 47. I would like to use the original gauges in the cab.
Is this possible?
I have seen that there are 12v conversion adapters to go from 6v to 12v. But there are many different types of adapters and I am not sure which one I would need.
But would those work with the more modern fuel sending unit, temp sending unit, and oil pressure sending unit?

I would put in 2 six volt batteries in series and a 12 volt alternator. Then tap one of the batteries for the original gauges. The originals are probably positive ground but if you reverse the wires they work.
If you are changing sending unit on the gas tank you will have to step down the voltage with a resistor - check on the HAMB site - a lot of builders have done this. Some of them change the guts of the gauge to a modern unit and keep the original face.
Good luck

Piece of cake.
Use the original OLD Ford senders and use a reducer, like a Runtz, on each of the gauges.
I actually made my own reducers, using some 7806 voltage regulators and a heat sink. I used a BWD S330 sending unit for the oil pressure gauge, which is actually a 90# sender. Temp sender needs to be a single pole one for a pre-56, if I remember correctly.
Start with a LM7806 voltage regulator
Red is 12v in, black is the ground bleed, and white is 6v out. Regulator is screwed to an aluminum heat sink
the BWD S330 sending unit for the oil pressure.
Shows them installed on my '40 coupe's instrument panel.
Hope that helps. Feel free to e-mail me with any questions. bret@streetrodder.net

Or you could use this part from Mac's
Ford - Ford Voltage Reducer - Reduces 12 To 6 Volt - Ford - Dash Gauges - Macs Auto Parts
Part #: 47-62256-2
I just converted to 12v and that's what I used, works perfectly.
