ok i installed the gauge at the filter via a sandwich adapter(oil cooler adpater flex-a-lite) this is to run a bypass oil filter (you know the one every one should install ) but anyway. i'm not sure if i understand what you mean Cary please elaberate. the sandwich adapter is doing good no leaks but the filter assy is another story (maybe cause of the hight press. (the whole for my inquery)
i'll post a pic of the install tonight when i get home from work. but i have the outlet of the adapter tee'd off for the gauge. and that where the press. is taken from.
the pressure seems kinda high to me , maybe the gauge is erronious, also the gauge in the car reads normal but i resally dont know if that is accurate.i'll try to get more data as the project progresses
