I use a 35-40 Stipe Oil Pump on our 5-Main Engine.

The Engine has a Miller OHV Conversion, We hame an Earl’s Remote Adapter with a WIX 51085 Filter, the adapter has an 1/8 NPT output that oils the head, and we use Valoline VR-1 20W-50 oil. There is no internal or external pressure adjustment.

The engine runs with just over 30 PSI Oil Pressure, at start up, running warm, and at idle a when warm (165 degrees) pressure is just over 20, maybe 22 PSI.
