dumb question

[Oss]

I was taking out the amsoil air cleaner (like the K&N- spray with oil after cleaning)
and in the process of taking off the hoses from the petcock (thanks joe in STLOUIS for the flat screwdriver tip) I noticed that there was a clamp on the fat hose- which I dropped onto the  ground using said flat screwdriver and found this morning but that there was no clamp on the tiny hose next to it

Does that hose need a clamp and what exactly is that one attached to on the other end  #6 carb? If my rememberer is working that is the vacuum hose yes?

Not riding today anyway  fixed the pool and I am gonna be in the water till the heat of the day passes me by

Thanks

that little hose is what operates the vacum on the coverset of the petcock. before i had changed over to the pingle mine had a spring clamp on it

got it off and on ok,  runs great  Now I am good for another year or so.

far as I can remember that little hose never did have a clamp
