So I corrected the oversight - I drilled and tapped the elbow to add the port. Here is a picture. It worked great today when I flushed the pump to clear out the gunk.
Buying a freeze dryer in person gives you a better sense of how big it is, while you can also get hands-on advice from the professionals working at the store.

Options: consumer choices for this appliance are currently limited. There Know More are few companies making “home” freeze dryers, laboratory freeze dryers are built for scientific sampling so may not work as well for food, and the small commercial “pilot study” freeze dryers tend to be larger than those marketed for home use.
I've run the system in countless tests including over filling the pump and running the pump without a load (both result in lots of oil spitting out the exhaust port of the pump). I've drained the catch can twice, once with over 5 oz of oil in it, but have not collected any oil downstream in the jar so the system is performing well.
