Dale,

My psru oil supply comes off the oil cooler outlet using one of the adapters shown in the attachment.   This location is closer to the psru than the oil filter adapter block.  For the oil return, I drilled & tapped a hole in the rear rotor housing just above the oil pan mating surface.  Its easy to see where to locate the hole while the pan is off the engine. 

 

My tap & die set gives the drill sizes for common tapped holes.  Maybe yours does too.  Otherwise, do a Google search and print one out and keep it handy.

Mark,  is that adapter 37 degree flare?
