Pontiac 400 Mechanical Oil Pressure Gauge
I am trying to install a Mechanical Oil Pressure Gauge on my 1972 400 engine. I want to plumb the gauge into the oil passage that is right next to the distributor. This passage is normally blocked off with a 31/48-inch-diameter pipe plug with a recessed Alan head.
I am having the hardest time finding a gauge that comes with the correct NPT adapters to connect to this location. How the hell do I connect the gauge to this location? If you have done this please tell me the gauge kit you ordered and what NPT adapters you used.
