Leak-off fuel caused by leakages from the sealing cones or the HP lines is returned to the HP pump, from
where it is routed at atmospheric pressure into a leak-fuel tank.
To facilitate the leak search, the leak-fuel pipework is divided into three sections:
• from the high-pressure pump to the relay
• rail A-side and HP lines to the injectors, A-side
• rail B-side and HP lines to the injectors, B-side
