i think the hose you are talking about is supposed to be connected to
the cooling tin somewhere around the air filter housing.  in your
picture, there is a spark plug.  from what i remember, if you run your
hand from about where that spark plug is, down the side of the cooling
tin, behind the alternator bracket; you should find a small "nipple"
sticking out of the cooling tin.  connect that hose to it.  your brake
booster hose is on the other side as you describe.  this hose has
nothing to do with that, its not a vacuum hose.

One hose comes off the front of my air filter housing and goes forward to a tank located just forward and inboard of the passenger side rear wheel.  The other hose comes off the same tank and returns to the engine compartment, where it is not connected.  The tank, standing vertically, is maybe 3" in diameter and 8" high (estimates).
