Fuel gauge to oil pressure gauge???

So I have been giving this some thought and would really like to get the oil line (mechanical gauge) out of my gauge cluster and out of my cabin.

Been doing A LOT of research and I have yet to see an electronic oil pressure gauge that:
1.) looks stock
and
2.) fits into my gauge cluster(sitting on the center console).

So this got me thinking about how the gas gauge reads 0-90 ohms and oil pressure sending units send in ohms.....could this work?!?

I have the specs on the ohm range for the oil pressure sending unit and the specs for the fuel gauge. I am thinking this could be just simply putting a resistor in series to get the gauge to tell me what I am looking at?

Any thoughts, or has anyone else tried this??


oh, I have a 67 RS/SS.

Re: Fuel gauge to oil pressure gauge???

But why would you really like the oil line out of your cabin?
Do you think it's dangerous?

Re: Fuel gauge to oil pressure gauge???

What's the range of the oil sending unit?

Steve - It's not that it's dangerous, (although one could make an argument) its more a personal preference.

The range of the sending unit I have is a 0-180 ohms for 80 psi.
(an almost perfect 2-:1 ratio).

You would need to add a 180 ohm resistor with one lead on ground, the other lead attached to the wire going the sending unit.

Re: Fuel gauge to oil pressure gauge???

If that is where you want to go it - it is worth an experiment.

You know what your car reads with the mechanical gauge now at idle and at speed, you can dial in your experiment with a potentiometer in parallel and replace with a fixed R value once R is known.

I'm going to experiment the the Batt/Amp gauge one day to retrofit a Voltmeter in it's place. I just can't see the $120 for a correct looking V meter....

Re: Fuel gauge to oil pressure gauge???

That would confuse me having my oil pressure reading between Full and Empty. But that's just me. Ever thought of removing the guts from your mech oil gauge and replacing with guts from an electric gauge?

Re: Fuel gauge to oil pressure gauge???

I was the same.
I like the look of the standard console gauges but I preferred not to have the oil line coming into the car.
Still haven't found anything that looks like a stock electrical oil pressure gauge.
I ended up getting a set of autometers (as shown in the photo below), but if I could find an oil pressure gauge that looked standard but was electrical (instead of mechanical) I would get a set of the standard console gauges.

Re: Fuel gauge to oil pressure gauge???

Just wanted to do a quick update, for those that were interested. Here are some pics of the final product.
