Small vacuum connection

While checking my FPR for leaks today, I noticed a very small vacuum connection open with no hose attached. This is in the area behind the SC plenum, under the middle of the cowl. It is directly below a whitish plastic vacuum junction point which is bolted to the plastic beneath the cowl. It is black plastic, and has two small nozzles protruding which are vertically stacked. The bottom nozzle has a small thin black hose coming from the passenger side firewall attached, the nozzle just above has nothing attached. If I were to guess, I would say the hose/nozzle is maybe 1/8".. definately among the thinnest in the engine bay.

Anyone know what hose might belong here, and what kind of difference this leak could make?
 
I can't say what connects to those on the tree exactly but they end up at the vacuum distribution box. You need to pull on all of the small lines along the firewall until you find the loose ones and plug them in. Good luck
