Help! Air filter box vacuum hose
 

Can anyone tell me the name/part number of this hose on the back of the air filter box that is supposed to go into the front of it? I can't seem to find any information about it anywhere. Thank you for your time.

have you tried visiting a dealer parts web store to look at their diagrams? I use Tasca Parts but there are plenty out there just do a search for genuine volvo parts etc.

Found it!
 

After looking at I don't know how many diagrams, I finally found the part number.
