"real" oil pressure gauge
So last night I tried the real oil pressure gauge trick. I put a sending unit in place of the pressure switch and put a jumper on the back of the cluster for the oil pressure gauge. It works, not much movement on the gauge but instead of knowing you lost oil pressure when it gets low enough to turn the switch off at least now if it starts to drop you will see it happening and be able to hopefully stop before any damage is done.

Re: "real" oil pressure gauge
I wonder how your pcm will like that, it looks for an on or off from that sender.

It will stop running before you damage anything without oil.

Yea I knew that, but I was just curious. Wonder why Ford didn't make it an actual gauge in the first place.

Re: "real" oil pressure gauge
The PCM won't care since it only sees the Engine Oil Temp (EOT) from the low pressure soil side of things. The gauge/instrument cluster board is the only thing the switch connects to. Cheers!

Re: "real" oil pressure gauge
My gauge 'switch' used to act goofy so I checked the oil pressure at the reservoir and it was just fine. I did this mod and like it. Depending on the rpm and temp the gauge will show readings from the N to the L in NORMAL ( on N at hot/idle and around L at cold/idle) and usually sits between the R and M above 1500. Even though its not scaled, it now provides a pressure reading-- so like the OP said, its easier to know if something starts to go wrong.

back on topic: OP, do you have a part number you used for the oil pressure sensor? I am interested in doing this mod as well.

Re: "real" oil pressure gauge
Sending unit out of a Ford with a 400 in it. I used a 80 bronco. You need to take the 20 ohm resistor out and replace it with a jumper on the back of the cluster.
