    How to replace an oil pressure sending unit

    This video shows where the oil pressure sending unit is, how to do a simple test, and of course how to replace it.

    Thanks for this Steve! So the corvette unit has the correct calibration for the gauge?

    Yep. Its calibrated for 80 psi and works nicely. Plus, if you buy the thing at AutoZone you get a nifty lifetime warranty.

    Nice! Look forward to installing mine!

    For reference, typical oil pressure is high on these cars. At an 800-900 rpm idle when hot, you can expect to see the gauge just below the 3:00 position. Anything higher than 1000 rpm tends to push it to almost 80 psi.

    My reproduction sender from DMC is mfunctioning. When the car is hot it reads at the quarter mark under acceleration. Sometimes it twitches up. I may try this one.

    Thank you for this! I just replaced the sending units on both of our DeLoreans with the AutoZone units, and they both work great! There's no more of the gauge being pegged at 80 or straight up at idle.
