    Hello all, was wondering if anyone has a part number for an oil pressure sending unit for the optional rally gauge for a 1975 Regal. All I'm finding are the ones for the idiot lights. Thanks, Mario.

    You could use virtually any gauge sender meant for an oil pressure gauge on a GM vehicle. They make 60 and 80 psi senders, so gauge operation might vary somewhat, but so what? The concourse guys get obsessed with the absolute correct sender. Again, do you really care about that? I would just correlate the readings with a good aftermarket gauge if you want the gauge readings to matter. You can easily find a sender on EBay.
    Something like this,

    Here is a thread that might help,

    Thanks Larry. I thought I had the correct one from one of the parts suppliers and it did look different from the other "Light" sensors. But after I installed it and saw that the pressure gauge was still not working I found out on another site that that one was for the idiot lights too. I also found the problem with my other rally gauge. Upon closer inspection I found that one of the printed circuit lines was burned. It was the one that goes to the grounding pin. I will try to repair it with a piece of copper wire and solder.
    All the best, Mario.

    If you need a new printed circuit, I should have several along with full gauge assembly. PM me. Actually if you need the gauge, you can have it for the cost of the ride. If you're going to try and repair yours, I wouldn't solder it you'll probably just melt the plastic. You can try a rear window defrost repair kit and repaint the line back on. Jeff

    I think that you need the one on the right. I sent a PM, but can't attach photos. Jeff Gauges 002.JPG

    Actually Jeff, I just looked at mine and it is exactly like the one on the left with the eight pin terminals.
