Rubber hose to breather

[jae12]

Does any one know what the hose running from the side of the breather box to the motor is for ? I'm trying to snorkel it and want to make sure theres no leaks.

Thanks in advance

#13 is the crankcase breather tube. As long as you do not alter it, it should be fairly sealed.
