Oil Filter Plumbing

OK, after digging all weekend in the forum I'm totally confused so I need your help.
I am suffering from low oil pressure readings in a newly rebuilt engine. I used a mechanical gauge at the location of the electric sender.
I have a 288 that does not have an oil return drain hole in the crankcase. I need to know how to properly plumb the oil filter to the engine.
Also, I would like any opinions on other causes of this condition...did I leave out an oil galley plug somewhere?
All help is appreciated,
Mark

I should also mention that I'm using 10/40 oil.
