So i researched this, and people said it shouldnt happen, but i'm not sure if its a big deal or not. removed the canister, hose to the right of my finger is leaking on the engine. Looks like the hose is coming from the fuel tank. Last ride, it was an orange color, todays was a blueish green color. At first research i thought this was an oil breather hose from the crankcase, and that i was overfilled with oil. When i lifted the fuel tank the hose leads there. So is this a big deal? If not should i just plug up this hose or keep letter her drip? Thanks guys

What did you do with the hoses when you removed the canister?

Let see they came off with the canister, i threaded bolts into the throttle bodies, and the last one is the one pictured. I also read that sometimes when you fill up it will do this, but i have under half a tank.

I am pretty sure that vents the gas tank so you don't want to plug it. As fuel comes out of the tank air has to go in and it can't get in through the gas cap. I am trying to see if I can find a picture of mine but there is some discoloration on the engine from the hoses

T connector it into the line that hangs below engine

I got 2 hoses off the bottom of my tank. I Y'd it and ran it down by the bottom shock mount.

It was leaking before the canister removal, you just didn't know it.  The internal hose that feeds that vent is boogered.

It was orange because that is the color of varnish, it is now bluish-clear because that is the color of "good" gasoline.
