Ok, I do not understand the point of or even the purpose of that TF system. It looks like an over complicated pain in the ***.
You do need a quality air/oil separator with a good working PCV system. From the looks of what you’ve got, your pulling vacuum for the brakes through the same system. That makes no sense.
The vacuum for the brakes needs to be hooked to the intake manifold, with nothing else running off that hose.
The PCV valve needs to be hooked to the back of the carb on the 3/8 nipple under the rear float bowl. You hook the PCV valve there so the carb sees the controlled leak and not just having an air leak to the intake manifold.
So the OCV hose goes from the back of the carb, to the separator and then to the PCV valve. There should be nothing else in the system.
Also, the best investment you can make is the ME Wagner adjustable PCV valve. There is nothing on the market like it. An off the shelf PCV valve (universal fit) universally fits nothing.
With an adjustable PCV valve you can tune the system to fit your combination.
