Where can I find the oil pressure sending unit on a 1986?
Oil pressure readings all over the range when car heats up, I hope it is just the sending unit.

It's on the back of the motor. just about dead center. Between the manifold and the firewall.. it's about the size of.... Ummm I dunno a little smaller then a tiny paper cup.. it's silver and has a wire coming right out the top.

It is located on the left side of the distributor. Remove the wiper motor and you can get in at it.

Actually, one is for the digital dash readout and the other is for the FUEL PUMP RELAY. If the oil pressure gets below a few pounds, the fuel pump loses power.
They say a picture is worth a thousand words:

Hope this helps you out!

I replaced my L98 sending unit last Sat 21 Jul and it took about 1 hr, that is taking out wiper motor and wires from distributor,other then that it was a piece of cake, good luck, oh I did use a medium sized channel lock pliers to unscrew and put back in,

Almost 19 years later..
Reviving one of the oldest threads I've seen to ask a question.
This area of my car caught on fire the other day. The "fuel pump relay sensor" is melted and unusable. It took me a long time just to find this thread where someone correctly identified this item in the first place. Other threads were saying it was a temperature sensor. I even found an LS swap thread that referred to it as a temp sensor.
What is the correct name or part number for this "fuel pump relay sensor" and where do I get one? Is it just a temp sensor being used to trigger the fuel pump relay? Tell me it isn't this very expensive sensor.

Sensor
It is an oil pressure SWITCH.
the body of the switch is grounded, and when the oil pressure builds a few pounds, the switch makes, and provides a ground for the fuel pump incase the Fuel pump relay fails.
that way, the fuel pump has a second path to energize, keeping you from being stranded
