Rigid copper 1/2" water pipe will never rust, and oddball shapes can be made up with sweat-soldered fittings. Then a short piece of rubber hose on each end can be used for connecting to the manifold and booster. A little flat black spray paint takes care of the copper color. Not original, but long-lasting.
