6th Gen - What is this hose supposed to be connected to?!??

6th Gen - What is this hose supposed to be connected to?!?? - FIXED, THANKS

I just took lifted up my gas tank to check/clean my air filter and when looking around, I noticed this hose (pic), and it was not connected to anything. I looked around trying to find a second hose to connect it to, but no luck.

Can someone please check their bike and see where it runs to?? This picture is on the left side of the bike, where the PAIR valve is. EDIT - HOSE IDENTIFIED AND FIXED> THANKS ALL.

 

that's the fuel tank vent line. If you look up underneath the tank, back by the fuel pump plate, you'll see the other half.

 

Those vent lines must be hooked up because they may have vacuum on them.
If you have a vacuum leak it could make your bike run lean.

 

There is no vacuum on that line, it is a simple vent. however, if the top portion gets pinched shut, the fuel pump will collapse the tank.
