With that in mind, if your actual engine oil pressure is 10 psi due to a failing galley gasket, your gauge might show 20-25 PSI, which hides the problem and may result in a spun bearing / new engine... and no one wants that!

I do plan to eventually relocate the sensor to tee off the oil return line to the block. But for now I’m not concerned that it’s giving me a false reading. Pressure drop in the filter should be 1-2 psi and in the cooler probably about the same at idle. Therefore I think anything over 30 for a pressure reading is totally normal.
But to your point… reading pressure after the cooler and filter would giving me the reading that really matters… what’s going into the engine.
