Vacuum Pipe issue

Can someone help please,

I’m trying to locate a correct part, to attach a vacuum pipe. Unfortunately I have now completely failed and need help from someone who knows what’s where

Basically, the pipe I have is attached to the air filter box (outside) I think it’s called a Vacuum Air Pump - Solenoid Valve. The valve itself it’s not big, and it has 2 vacuum hoses attached to it. One on its side and another to the bottom.

If I follow the diagram, most obvious part that resembles what’s on picture is some sort of Air Valve or Pressure Valve at the back of my intake Manifold. Does anyone know, If this unit has a “pin” to attach a pipe to it? I did take a picture of mine when I replaced PCV on my car, but as far as I remember I didn’t see anything on that valve that would remind me to plug the vacuum pipe. Maybe I’m wrong, but please if anyone knows about this issue, let me know.

here is another picture:

the pipe in white is attached to the Vacuum tree, but there is another pipe right under it. (in black) where does it go?

Just for records: my car is Volvo 850 (Auto) Without Turbo - Automatic 2.5 / 20v /Petrol / Saloon / Engine: B5254S

In my previous post I have mentioned that one (White) pipe is attached to the Vacuum tree on manifold, this is not the case, it’s attached to the small valve that splits the pipe in 3
