Wow - a whole lot of non-useful replies there... 
That hose, which is often missing, attaches to the drain at the bottom of the air box, as has been pointed out. The other end of it is to be fished vertically through a hole in the body directly below. That way water that gets into the airbox (like from driving in the rain) gets neatly diverted to the road below, just in front of the splash pan.
It actually is an important connection. Without it, water gets put into the space forward of the kick panels, and may or may not find its way to the drain hole.
AFAIK, all buses have these, or at least did have them. |
So you are saying the exit hole for the tube is directly below that spigot?
I didn't find one there but I did feel a hole that felt like the right size over by the steering box. I'll look again.
I have no idea why my spigot is so crunched. |

What a perfect photo for that!
That's interesting. It seems that they moved the hole from over the steering box more towards the middle. My experience is based on '73 and later buses. Hoses are not that long, and would not allow for water to collect in the hose like that one.
I guess the answer is to just feel around until you find the damned hole! 
You know, somewhere (and this may already exist) we need a comprehensive list of what all changed and when for the Bay Window Bus. All the way down to little details like this.

I agree...these are the little changes that the Bay's went through. I wonder if my 79' has this same drain hole...I know the front end clip was replaced.

If would make sense that if you have nose vents there is some sort of drain in the system. |

 I think the relocation of the hose towards center corresponds with when the splash pan (pedal cluster cover) receieved a large hole, approximately the diameter of the hose in question.

I went to Home Depot and got this hose in WHITE.
BRAND: EVERBILT
6ft BILGE AND PUMP DISCHARGE HOSE
+5*F to +150 *F
1-1/8" ID
upc is 8 11000 01190 9
is on the label
I cut the good ends off of my 50 year old hose and those pieces entered nice and firmly into this hose.
I suppose if you did not have a crappy one with holes in it, you could still make this one work... $8-ish, IIRC

I ran into this issue many moons ago on my '69 singlecab. original plastic was all beat up cracked etc.
There was no repro made - I found a washing machine drain hose works great, just about the same size.

Moments ago listed a hose that was sent to me by one of our favorite used parts vendors. I asked for one to be sent for my 1968 DC and found the "replacement" had two extra segments making it longer than my original. I asked what year bus he removed the hose and he replied 1973. When vendors selling new hoses suggest theirs fit 1968-73, I have significant doubts.

It’s corrugated bilge hose sold at every would-be marine store in the world for a couple of bucks a foot. What on earth would possess anyone to buy a 50 year old piece of plastic that will soon look just like the one removed. Buy some new hose, heat flare the upper end and cut the lower end at an angle. It will look and function EXACTLY like the original. I’m all about keeping my bus original, but some things are just stupid. I have some NOS tires and oil that I’m selling. PM me.

Shouldn’t RHD vehicles discharge the water on the other side?
