Depends on the sensor/sending unit some are single gauge and some are for doubles. I replaced an oil pressure sending unit with what was thought to be the correct dual sender, the gauges (Stewart Warner) read less than half the normal pressure. The product numbers on my old gauges were 30 years old, had been superseded several times and the cross reference was hosed up. Took trial and error to find the correct sender.
Might be easier in the long run to buy a matched gauge and sending unit if you have an extra oil port to screw it into.
