Ah... that explains the high pressure.
If the oil pressure gauge is mounted before the oil cooler, it is also mounted before the oil filter.
So... your actual engine oil pressure = pressure drop from the oil cooler - pressure drop from the oil filter - pressure drop from the fittings/lines.

Using real numbers, with a 10 GPM flow rate as an example (not uncommon for an engine running 6000 - 8000 RPM), the 20-row Series 9 will introduce a 5 psi pressure drop from inlet to outlet. (Note that a single 90 degree fitting in your oil line could cause more restriction than that.) The 25-row Series 6 will cause a 2.6 psi drop. .
It would be interesting to see the oil pressure with the sensor mounted to the engine for those that have an engine oil cooler - only then is it measuring the internal engine oil pressure after the cooler and after the oil filter.
