Fuel Tank Vents on CA model

Does anyone have a schematic for the fuel tank on a CA model? I am looking for the internal routing of the two vents at the bottom of the tank. Thanks.

While I don't have a schematic, I can tell you that one goes to the hole by the gas cap for overflow and the other goes to the inside of the top of the tank and ends at an opening that allows the gas from the CA emissions BS to drip back in. Here is a non-CA tank from a Kawi Ninja 250. Too bad it only shows the overflow pipe.

The one on the left is the vent, the other goes to the emissions.

On a CA bike, they both actually go to the emissions (little R2D2 looking round can). The easiest way to double check (although it is probably the left as dariv said) is t oblow compressed air into each nipple individually with the gas cap open.

OK Mr. know-it-all.......
Correcting people on here is my job...
I don't really remember where both tubes went once they left the tank.... I do remember thou, that the left one is the vent.

On a CAL bike both of those vent lines do go back to the emis canister. Tha left one I think is marked with a blue band goes to the little nipple grommet at the base of the fuel cap. The one on the right with a red band am not sure how it inter connects with the tank, just know that it is internal.

04-3,200 miles bought July 2011 with 928 miles. Loaded with acessories to many to list here, see my albums for more details! I also make a custom tank bib specific for the 750 if anyone is interested, ck my albums for some pics.
