How about some more details on the Fitting used for the Oil Pressure Gauge and the Oil supply to the filter.

IP return is M14x1.5 to #6 JIC

T-fitting, purchased on Ebay from UK...M12X1.5 male and female with
1/8" NPT...the 90* fitting is 1/8" to #4 JIC..

The filter in and out are both M12X1.5 to #6 JIC

1/4" ID hydraulic hose

Thanks again for all the help you gave me with this project

This infomation is in some of our other threads and also in the Manual.
The Bypass Section of the Stock Oil Filter has nothing to do with the Bypass Valve that is built into the Oil Filter Housing.

The normal pressurized Oil (the Full Flow section of the Oil Filter gets Oil from the same area) on the out side of the Filter goes through the bypass Section of the Oil Filter and through an about 1/16" hole at the top of that Tube that goes down the Middle of the Oil Filter Cap.
You can see that Hole when You pull off the Cap during an Oil Filter Change.

The Oil continues down the Tube and goe by a Spring Loaded Check Valve that is inside the lower end of that Tube and from there the Oil goes Back to the Oil Pan.

IDLE OIL PRESSURE NOW SLIGHTLY ABOVE 2 AT OPERATING TEMP.
I ASSUME BECAUSE OF THE EXTRA 2 QUARTS OF OIL AND COOLER OIL

Thanks for all the info guys, an enjoyable read!

Sorry for not having read the whole thread, but I recently bought some 2 micron (absolute) spin on filters for around $10 each ($15 each including shipping).

CIM250E02-70819 Cim-Tek 200 Series Fuel Filters

Cim-Tek 200 Series Fuel Filters - 250E-02 70819

They are fuel filters (diesel & gasoline) but should work fine for motor oil.

Fuel Filters are not made to take the amount of pressure. In the Manual a Turbo Diesel can get as high as 110 pis (then the Pressure Relief Valve opens in the Oil Pump).

On My own Engine I got about 97 psi max.

Then there is the Heat. The Oil can get over 200 degrees F. If the adhesive inside of the Fuel Filter that holds the Element together melts that is a bad thing.

If you use them as Oil Filters please let us know how it turns out for you.

Good advice. I am using them to filter fuel. I'll see what the design specs say.

110psi! Heck, the hydraulic filters I have are only rated to 50psi!
