Oil filter relocation kit

The pipe plugs take a 5/16 allen, the thread size is 1/4 NPT(pipe thread). You can get whatever fitting you need to go from NPT to AN.

In a dodge ram forum i read that someone had 35psi after oil filter relocation another gentlman claimed to have drilled and tapped them larger i was under the impression oil pressure was really made with the pump amd bearings?
This maybe my true question here.. My relocation mount is 10an. 1/4 npt to 10an seems to be a very small fitting to a large fitting and possibly restricting should i worry about a drop in pressure because of that restriction? i always thought oil pump (im using a melling oil pump with the 65 spring i believe it was) and bearings (i had everything rebuilt) is where oil pressure is made?
