Where does this tiny hose connect to? It travels from the air filter box to I presume somewhere on the engine block. I own a ‘06 V70 model & just installed new starter. In doing so, this hose came unattached. Thanks in advanced. Yes- I can figure it out based on its length but thats no fun.

 

Just saw this.
On the intake manifold you can see a braid covered hose, a hose with a yellow stripe and a clamped hose extending out-of-the-picture to the right.
There's a nipple there for that right-angle connector.

That line provides vacuum drive for the air temperature blend door.
