Bob same thing happened to me, I think it was an internal check valve, sent it back to Booster Dewey and he repaired, no charge. It had also been about three years with very little driving. Have fun getting push rod off the brake pedal.
Dakota Digital # ODYR-40-2/SLX-40-2 ,2 1/16 Dia .is a multifunction gauge W/alarm set points. Looks like what I’m looking for. Gets a bit $$$ after adding transducers. Looks like it may fit in clock location.
I’ve been looking for a digital gauge that could be mounted under the ash tray door. I would like the readout to be able to cycle between oil, temp, and maybe amps with preset alarms. Has anyone seen one like this.
