Thought I would post what I did for a fairly clean looking steel fuel feed line routing on the small Holley 4160 600 with the fuel inlet on left side. I bought this fitting from Summit https://www.summitracing.com/parts/sum-g1527/overview/ . I removed the hose fitting that comes on it. I bought a pre flared steel line from my local auto parts store and used a bender. I love the way it turned out. It looks kinda stock but it's low and out of the way.
