It's dropped. Not too hard to get off. Hope to have it back together in about a hour and a half. Haven't found anything yet to indicate something. Putting my stock oil pump back on just to be sure. Removed the pickup tube, blew it out, nothing. Looking to be the sending unit possibly or the oil pressure regulator, wherever that thing is.

Oil pressure regulator
Oil pressure regulator is inside the pump. The socket head plug holds the spring and plunger in. I have seen that problem pop up before (Stuck oil pressure regulator plunger) especially on after market pumps. Do a search on low oil pressure. I would replace that pickup tube o-ring while you have it down. You've already eliminated the Oil and filter.

Got it all back together and it's running. Finished about 2:15 this morning. I swapped out the TR pump and put my stock pump back in. Pressure did get better, but still not where it should be. So basically, I think I have eliminated the pump, pickup tube screen, filter, and o'ring. It's now falling on the pressure sending unit. Plan on picking one up at the dealership in a few. Looks like it's a pain to get to. I guess the work I did last night was just piece of mind. I was bored, so......
