    I've notice lately my Gauge Mark oil pressure gauge doesn't return to zero with key off. Seems to work OK otherwise, hot 40 to 60lbs oil pressure. I just thought I remember it returning to zero when I turned off the car. Any ideas? TIA.

    Disconnect it at the sensor, see what it does.

    I believe I just never noticed this. Gauge sits at whatever the oil pressure was when car was shut off. Turn car back on and gauge returns to zero until engine starts and sender sees oil pressure. I believe normal operation, I just never took notice of it.

    I had a TA that used to do this. It was oil press, temp and tach that would stick and my OCD wouldn’t let me leave it like that. So I always had to cycle the key after shutting the car off so the gauges would “zero out”

    I used to have my Stewart Warner 2-1/16" mechanical oil pressure gauge where the clock is. It fit perfect with sponge around the back side for support.
