What is this for exactly (pic)

On my 05 cbr 1000 whenever I ride it or start it for any amount of time theres always smokey fumes coming from the gas tank mainly when putting new fuel in, and when I turn the bike off there is ALWAYS pressure you can hear trying to escape.

In the picture I posted the outlet with no hose on it had one on it but it kept getting pinched so I removed it, and it still has this pressurizing symptom. Also when I unplugged the other smaller rubber hose coming from the fuel pump assembly no pressure got built up. Can I just run that breather tube to nothing because it seems running that breather tube to the other ones is causing a clog somewhere and I couldnt locate it.

If you pull that hose off the tank nipple and blow through it, is it clear?
Does it go to atmosphere or somewhere else?

That hose is clear I pulled it off but it's connected to a T connector that has two other hoses on it.

I believe that large nipple is the tank overflow, and should drain to the ground or maybe to a container. If it goes to a T, I guess I'd follow both ends of the T to find out where they go.
Put a hose back on that nipple, and blow through it - air should come out of the little hole right next to the filler hole under the gas cap. It's meant to allow overfilling to drain through that hose instead of all over the outside of the tank.

I believe that small hose is the tank vent. You should be able to blow through that one also, but it will be kinda hard, maybe impossible unless the gas cap is open.

Okay and I know the bigger fuel overflow is clear because I rain a wire through it from the top and it didn't get stuck or push anything out. And as for the smaller one it didn't build up any pressure when I left the smaller hose off it and I might leave it off but I'm concerned because something somewhere isn't breathing. I'll have to follow them and report back.
