is the black hose coming back from the catch can??
If the can has a filter (open top etc..) this is not needed.
If it were a air/oil separator then you would as it would have no vent.
at position B there is a one way valve the stops the engine from pressurizing under boost, you could block this on the inlet manifold and run the black hose to the cam cover and block the turbo inlet pipe.
By doing this the engine will only have the pressure generated in the crankcase to vent out the 2 outlets, no vacumn from the engine will be able to assit this, I think this is why some people use air/oil separator as opposed to vented catch cans.
