What about going to the auto parts store and buying some silicon tubing to go over your fuel line? The stock fuel lines normally end up cracking from sun exposure anyways. What I did for my fuel line was use black rubber fuel line for a car, then put corrugated wire loom over that, it gives it a nice look and protects it as well. The wire loom I bought at Wal Mart it was about 3$ for 6 feet of it. Here is a picture of what I am talking about.
