If you are going to use the manifold and want a nice appearance, use stainless. You can always make up an AN flex line as well. Or get a length of 5/16 or 3/8 steel brake line. Make up the replacement to match the current copper line Copper work hardens and becomes brittle from engine vibrations and can split.

Others may have differing opinions but for safety's sake, copper is never used on fuel or brake lines.
