In your situation, the stainless steel line is a solution looking for a nonexistent problem. The plain old butt-ugly dark green copper/nickel generic fuel lines that are available at the corner parts store would be a much better choice, at a fraction of the price of stainless. That line is durable, rust resistant, and much easier to bend and shape to the correct form than stainless. Win/win/win!
