Can’t seem to find a oil pressure gauge that uses the metric thread and non pipe thread style fittings like the factory pressure sensor does. Trying to add a mechanical gauge to the car to keep an eye on things...

The factory port is M10x1, but 1/8 27NPT will work, with a little teflon tape.

The teflon tape is no problem if the gauge is mechanical, but if using an electrical sensor you may need to ground the sensor separately.

Where is the factory port located?
