GTO- to answer your question, I do not have anything done to my bypass. Also, the Fram HP2 has always been on the stock oil filter adapter.
I have a comment and a few suggestions.
1. Turning the oil pump with a screwdriver and getting oil out the hole for the adapter only proves that the shaft isn't broken, and that unrestricted oil can flow about 6 ".
2. You may have a serious oiling problem, and I wouldn't recommend starting this engine again, with anybodys filter until you prove a couple of things.
3.Put the oil filter adapter back on with any unpoluted filter. Use or borrow or make something to spin the oil pump through the distributor hole(as in priming ).
4. Have you done this before? The reason I ask, is that when you use the reverse on the drill, you can definately feel when oil pressure developes. Sometimes the drill will start to smoke (good oil pressure) If your drill spins effortlessly, you have some sort of internal problem.
5. Remove a valve cover and listen to the oil, you can hear it coming through.(do the pass side valve cover,as it's the last to get oil. You should see oil coming out the pushrods as it works it's way to the back. It may be necessary to turn the engine over by hand every once in a while to insure all the passages are getting feed.
6. Once you've proven that your oiling system is functioning, you can put on different filters to see if things change.
7. If all this is normal, and shows no problems, then procede with startup.
8. I have always been told not to break in the engine with synthetic products, and recommend using a quality 10w40 or thicker regular type oil until this is figured out.

One other question, Where is your guage hooked up?
