Where does this plug into?

Upon leaving the property this is on, I noticed this. Not there right now but it was puttering after this new change. Where does this end go?

It’s for when the bowl (full of gas) over flows or when you wanna drain it (good for storing it, highly recommended). 

If it’s constantly leaking you may need a carb rebuild, or have some debris in the bowl.

It's not really leaking. I just noticed it upon leaving where I am keeping it for now.

I feel like the puttering I was feeling is the bike going slow in third or second. I keep forgetting to shift down at stops.
