carb vent hoses

[dylandrew1]

Greetings,
I just purchased 3 FCR carbs that I plan to re-sell (non-outlaw bikes). From what I understand, 2 would fit a 08 450 S and the other one would fit a 450 MXR. There are extra "nipples" on these that I'm sure where they go. Can anyone help? Here a couple of photos below:

Any help would be greatly appreciated.

From my repair manual, it looks like the top pic is a breather hose fitting. The second pic, my 08 doesn't have anything there. My 09 has a big hose attatched there, I assume it is a vaccum line to operate the fuel pump. I'm guessing here. It is a big hose like a fuel line and heads up towards the front of the quad. Thats all I know.
