Where does this vacuum line go? (Diagram)

Hi guys. On my machine hose #31 just dead ends under the seat on top of the air box. It's sucking dirty air in the carb all the time. I'm pretty sure that's not what it's supposed to be doing. So do you know what hose #31 hooks up to?

Thanks!

It goes to the petcock/fuel valve. Some people have a raptor 660 petcock if you do the you just need to cap it off at the carb.

No that's not the vac hose. It's a vent.
It should just run back towards the airbox like you said. I think it has a clip that holds it on the snorkel plastic. Either way it don't suck dirty air into your carb.

Does it go inside the air box? Mine is just laying between the seat and the top of the air box lid.

To be fair to Kooter, my petcock vac line was also pulled off when I bought it

Thanks!

It tucks in to the side of the snorkel tube, actually the cap I on the snorkel . It does not go in the air box or tube..

Oops, sorry, I thought we were talking z 400 here, not sure where it goes on an eiger...Still, doesn't really matter where it goes, but I would have the top hanging down, so water doesn't directly fall in it...
