I looked into stainless braided flex hose instead of stainless hard lines. It was easy to find the correct length hoses and fittings, but none were DOT approved. Finding DOT approved hoses would be more difficult, and would drive up the price. I ended up ordering preformed stainless hard lines from SSTubes.com ($45 shipped) and 8 feet of 3/16" stainless tube armor from Amazon (~$12 shipped).
