Hose from air box (Duct) ?

I have a VN 750 A2 1986. In the front of the duct there is a thick and a thin spigot. Does anyone know where the thin hose are to be connected in the other end ? This hose is 18 inches long and the inside diameter 0.24 inch. There is an S-shaped bend in one end. Spare part number is 92059C.
Hope my english is understandable.

If your Vulcan has the charcoal emssions tank, the hose probably goes to that. If it does not have the tank, the hose is routed along the inside of the right frame and then lays along side the oil filter in the front of the engine.

Hi and thanks to Vulcan1999
I do have a charcoal emissions tank (guess it's the same as the canister behind the engine?) And the hose I have buy (partno. 92059C) can not reach from the duct to the canister.
Any other proposals ?

Here is another possibility. The hose could be going to vents on top of the carbs.

This sounds like the condensation drain line from the air box. Though I don't think mine has an S-bend.

This line runs down the right side frame tube with metal clips holding it and just hangs with the end open, to drain condensation out of the air box.

It's there, in the same area as the crankcase vent, but on the right side of the bike. (left side when looking from the front) Would be all the way to the front of the airbox, coming out of the lowest point. About a 1/4" hose.

There's been a few posts mentioning it in the past.

yea.. its not a condensation hose though... the hole doesn't go all the way inside the aire filter housing... its the carb vent hose, which allows the slides to function
