Hey Tag Welcome to the forum!

It seems as if the hose you’re showing is either the Vacum hose that goes from the back of the Intake manifold to the Vacum Canister that sits to the right of the starter Under the intake manifold
911400


OR it’s the Vacuum hose that runs from the Fuel Pressure regulator (Fuel Pressure Regulator is attached to the Fuel Filter) see attached Photo
911401


and that hose runs from there runs to the bottom port of the F connector that goes into the Intake boot
(Labeled SMALL hose in Photo)

The other end is connected somewhere under the air intake manifold
If that's the case I would assume the end you're holding attaches to the back /firewall side of the intake manifold. The other end most likely is attached to your vacuum canister which is indeed underneath the intake manifold directly to the right of your starter as you're facing the vehicle.

Do you know where to attach it at or could give me a picture?

I can try and get you a picture of mine. I have a 330xi so I'm not sure if it'll match up 100%. Give me a minute and I'll go see what I can see, just got home from work lol

Picture isn't mine, but I used this to replace the CCV system this last Saturday. That top one labeled "vacuum reservoir" is where I'm thinking that hose should attach to.
