I just bought some 3" blue silicone hose from Baker Precision (www.bakerprecision.com) out in California. I forget how I even found them, but they've got different sizes and colors plus have things like reducers, elbows, etc. I ordered on-line, got a confirmation on the same day and had the hose in my hot little hands about three days after that.
