Joe,

On my 3-rotor, I feed the coolers first, then to the oil filter, and
from the filter into the adapter block (rear iron).  Some older
engines have the "oil in" at the bottom of the rear housing, so a
single tap may work.  I also have taps on the adapter block for oil
temp and oil pressure sensors.

I initially had one drain on the RD2-C, but went to two when I had
seal leakage problems.  Not sure it was really necessary.  You can
drill/tap the foot of the #2 rotor housing for the psru return.

The oil from the pump comes out of the front cover and returns into
the rear side housing.
