Hi, fellow rotary enthusiasts....I am getting ready to run the oil

supply

line to my Ross PSRU.  I am contemplating tapping into the 90 degree

oil

filter adapter which we made.  Upon looking at several schematics

showing

oil flow and direction in a 13b, I concluded that the oil first

enters

the

oil filter from the port furthest from the engine, then after

flowing

through the filter, returns into the port closest to the engine.

Because

of

the design of my 90 degree filter adapter, it would be easier and

more

practical to tap into the system where the oil is returning from the

filter

back into the engine.  My thinking is that since the oil filter is a
"closed" system, that there should be the same, or adequate oil

pressure

just as the oil is exiting the filter as it would just before

entering

the

filter?  If this is true, I can tap into that portion of the loop,

and

have

a simple, short hose going straight to the top of the PSRU.  Did I

mention

that I like things simple?  Thanks in advance for any and all

replies

and/or

suggestions.  Looks like this thing will be making noise very soon.

Don't forget the .040 restrictor will cut down the supply so it

matters

little after the oil cooler where  you tap off the oil supply for the

Ross.

The oil may lose a bit more temp in the oil cooler so down stream of
that might help slightly.

Paul Connor,

Can you show how your going to tap into the adapter - I assume into the
front side of the return.
TIA

Sure, George....A picture is worth a thousand words. I drilled and tapped
the 90 degree oil filter adapter today for a 1/8" NPT.  See pictures. Hope
this helps. Paul Conner
