Whose PSRU is this?  Must not be Tracy's as it has an oil drain? Don't they normally do all the machining on those gear sets BEFORE they
harden them to diamond??

This is my PSRU.  An incomplete one-off that I bought with my engine.  Based on the same gearset, but a different design from Tracy's.  The oil outlet is one of the incomplete tasks.

I was looking over the problem last night, and I think I'm going to sidestep the drill-through-case-hardened-steel conundrum by simply drilling the outlet in the much softer rear housing.
