Yeah, when I went to check mine last year it broke off in my hand... probably the origional one from '89.

If you do happen to replace the hose, I can tell you from experience that getting to the end that connects to the crank case is a bit of a pain. Either that, or my hands are just too big to fit in those small spaces. I was able to get to it by removing the oil filter and got to it from the bottom.
