87 YJ Firewall vent or hose. What is it?

Sticking out of the firewall on the passenger's side of the
engine is very short piece of rubber hose maybe 1 3/4 inch
diameter. About the height of the valve cover.

Anybody know what it is? A vent of some kind?

Thanks,
Charlie

Is it near the heater box? It could be a drain for the AC.

I don't have AC (sob...)

It is the drain for the heater intake. Maintenance is to make sure that it
is free of dirt, leaves, and other junk. If it gets clogged, water will
come into the passenger/driver area. The one I have angles straight down,
and ends in a pinched-off affair. This is supposed to let water out, but
prevent exhaust and fumes from entering.

He said it is 1.75" in diameter, that is the size of a radiator hose.

It is also the size of the drain from the air intake box that sits in
the middle front of the cowl under the windshield.

I read the original post again, and "very short" could either mean that the
hose is broken off, or that it is the regular length of a foot or so. It
just depends on how long things are, on average, in his part of the world.

Thanks all. It is the air intake vent.

I should have said, by very short I meant an inch or so. Also that
it was open ended.

Is it supposed to have a cover or screen on the end? Mine is
just open.
