A line bundle replaces the supply and return runs together as one pre-formed assembly, which is the right approach on a vehicle old enough that both lines are equally corroded. Factory lines are bent to clear the frame, exhaust and suspension, so a bundle is not something generic tube can substitute for. On a WJ the failure is almost always rust where the lines run along the frame rail.
