Another weird question. Noticed a tiny hose broken, unfortunately don't know where it goes. There are 3 hoses coming out from the top of the crank case, from right under the cover, toward the front left of the engine. Two are 3/8 big ones, and there's a tiny one as well. I'm totaly lost to find out where this connects to, and this is not in any kind of manual. The think has been broken for a long time by the looks of it, and there's only a couple of imches attached to one side.
