what size is overflow fuel line

[Yama 1000]

I just noticed i have a hole in my fuel line that comes of the top of my gas tank. Can someone please tell me what size line is on my sled ?

That's just the vent, where's the hole?

The hole is up top above the radiator.

Yea I would replace it, you don't want gas leaking on top of stuff in that area. Just clip off a piece and take it to a store to match it up. Something else I do with mine is route it up the steering post then back down. This seems to eliminate the occasional siphon you get when you fill up the tank to much.
