It must've been doing that for a few weeks now and I just happened to be down there looking at the right moment.

What I can't figure out is how it happened. I installed the hose just where the old one was and I don't remember seeing any clearance issues with the belt before. So my question is how did this happen? Did I install the hose wrong?

Today everything was closed except for one shop that can get me a hose on Monday. Just trying to set up a game plan until it gets here.
