An improved fuel system conduit is disclosed. The fuel system conduits comprise an inner tubular liner and a substantially tubular cover comprising a metal band helically wrapped around said liner for covering and protecting the liner. The helical or spiral wrap allows fuel line flexibility while simultaneously inhibiting kinking. The helical wrap may also be covered by a plastic outer sheath.
