My air cleaner housing has a hose going to the oil cap and a little nipple thing inside that I’m not sure about. Does this mean it’s a California emissions model? I’d like to get a new one with the snorkel and have seen some with the hose outlet, but it looks like they have two. Mine only has one, so I’m a little confused where the other one would go. Also, there appears to be a little bit of oil in the cleaner housing, I assume feeding back from the hose. The little sponge at the outlet is a little saturated. Is this hose necessary at all? What if I were to replace the housing without it? The Non -California style..
