Here is another picture of the bottom of Chuck's Ross PSRU.
Apparently chuck is taking no chances with oil drain back 
from the PSRU as the drain appears to go into an electric
scavenge pump.

The only problem I can see is the blue AN fitting in the gear 
box could fatique and crack at the root of the thread if the 
drain back plumbing system experienced a resonent condition.

This would have the same result as if a feed line cracked.

BTW Chuck with the new thrust bearing how does the engine idle?
Do you get a rattle in the PSRU when the engine is less 
than 1000 RPM?
