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).

that's your charcoal cannister, for the evaporative
emissions control part of the gas tank.
the cylinder in the wheel well, that is.
it should have THREE hoses coming out of it ...
top has two hoses, bottom has one.
top rear one should be the one that goes to the air
cleaner (big nipple on the backside of the air cleaner
box, over in that front right corner of the engine
compartment). it look like it's going to the right
place ... the short hose in the picture.
the top front one  goes back to the fuel tank (this is
the emissions/vapor supply hose .. the vapors come to
the cannister via this hose).
the bottom one is your mystery hose. it should connect
to the fan shroud ... yup. on the air filter side, way
up top, there should be a connector for it. somewhere
around the alternator area.

Where should this be connecting?  Could it have
something to do with the brakes, which are spongy right
now?  The brake hose with check valve is on the other
side, I think.

nothing about the brakes ... that's on the other side
of the engine compartment.
all the cannister does is sort of store the gas fumes
from the gas tank and recirculate them into the air
cleaner box. the bottom hose is just a supply hose for
air from the cooling fan to flow a little bit into the
cannister to force the fumes up and into the short
hose/air cleaner.

it's like this only on the aircooled buses. the
watercools do it a little differently.

good luck!
