Oil Gauge Question
So after a lot of wandering around the internet (and parts stores) I've decided to modify an oil gauge from a later gm truck. I have pop rivets and my original oil gauge so I'm just going to swap gauge faces. The question is, hat year did gm switch from mechanical oil gauges to electronic oil gauges?

Not as easy as swapping faces as I believe the later gauge cups are bigger in diameter. What I advise is to trim the new gauge face (78-87 pick up) all the way up until it meets the cup and epoxy your face onto that. My other word of advise is not to remove the needle from the electronic oil gauge. You will never get it back in the correct position. Hope this helps, Tom

Re: Oil Gauge Question
I converted my Oil Pressure gauge to electrical using a mid 80s gauge and sending unit.
I had to modify the instrument cluster backing plate and the gauge mounting bracket to make it fit. I also do not have the original wiring harness, I have a Painless Wiring harness which already includes an electrical oil pressure circuit. The only thing I had to do was figure out which connection on the back of the gauge was hot, and which one was ground. The sending unit is much larger than most so it required a 45 degree fitting so it would miss the HEI distributor. I think it turned out pretty well. |

Re: Oil Gauge Question
Just wondering, why do you want to switch it out?

Re: Oil Gauge Question
I cannot speak for all but the main reason most people do this conversion is fear of the mechanical oil line breaking inside the cab and squirting hot oil all over.

Re: Oil Gauge Question
well with an oil line I have to worry about it breaking inside the cab or the leaking at the block. with an electronic gauge I still have to worry about a leak at the block, but being that a wire plugs into a sensor I don't think the sensor would leak unless oil is getting past the threads. Wires don't fail as often as mechanical lines. not to say they won't fail. I just haven't seen it happen as often. and with either you have to worry about the gauge going bad. I with there was a manufacturer that made both an electronic oil gauge and voltmeter that looked identical to the original gauges for people that want the stock look with the modern conveniences.

Re: Oil Gauge Question
I actually stumbled across your thread on those the other night and asked a question about hooking them up that you answered very quick and professionally. That's what got me wondering about why no major manufacturers jumped on board with this idea. Do you make oil gauges as well as volt meters?
