Eight high pressure fuel injection lines are routed from injection pump to an injector in each cylinder. The lines are of equal length but are bent differently to maintain equal length, prevent any difference in timing from cylinder-to-cylinder and aid installation. Lines are not interchangeable and are pre-bent by the manufacturer.
