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...
Where is the factory port located?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.
