Gauge install?
Thanks
If they were mechanical gauges, you would need to run lines each for coolant, oil, and fuel up to the gauge itself.
If they have sending units, they're electrical gauges. For fuel pressure, the easiest thing to do would be to remove the schrader valve on the rail and mount it with an AN to NPT fitting. For oil pressure, remove the oil filter adapter, drill it, and tap it. And for water, IMHO the best place is to remove the plug by the #8 cylinder on the passenger side head.
Also, I believe that is a metric thread, so I believe you will be needing an adapter. This is what I plan on doing.
NHRATA is correct about mounting the sending unit to the schrader valve with the necessary fittings.
Autometer has the fittings you need to run the electrical sending units for the water temp and oil pressure. The numbers are 2268 for the oil pressure adapter and 2277 for the other
