You can see fromt he Box they were previosuly sold as Bypass Oil Filters and on eBay they often sell the old adapter Plates for various Engines that Motor guard made.

The used Frantz Oil Filters show up more on eBay and it is hard to buy one fore less than $70.

Functionally the Motor Gurads do the same thing and can be had new for about the same price.

What I find interesting is even though the no longer market the Motor Guard Filters as Oill Filters they did not change the name to reflect the Air Line Filter use.

I chose the NTZ G-26 bypass system...It is NOS and has been updated to AL-29....Ebay cost $50.+ $14. element....AL-29 is $382. +$45. element
pictures 29 =oil return to IP...30 = oil pressure port.. 31=filter housing..Installation not ideal but works as it should. Considering other locations..
Now takes 10 qts. of oil....Baldwin P-102 standard filter. Can quickly be restored to stock.

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

1/8" NPT...the 90* fitting is 1/8" to #4 JIC..

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

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

Not sure what would explain that.
