It is probably that hose. I had the same noise on mine and that's what it ended up being. Rubber end cap was turned inside out, kind of damaged, and the clamp/hose was completely loose. I was able to pull it right off. Anyway I just removed the rubber endcaps, re-clamped the stock hose back on, and no problems since.
