🔌 Function

Holds fuel at injection pressure and distributes it evenly to each injector, damping the pressure pulses as they fire.

⚠️ Common Signs of Failure

• Diesel weeping or misting from a rail union
• Hard starting, rough running or a rail pressure fault logged
• Smell of fuel in the engine bay after running
• Corrosion or thread damage at the injector line seats
• Sealing cones scored or fretted where the pipes land

🛠️ Service Notes

• Check the engine serial number before ordering, since this rail is listed from serial number 2004008447 onwards and earlier engines take a different part
• High pressure fuel lines are single use in most cases, renew the pipes rather than reusing them and never work on a pressurised system
• Cap every opening while the rail is off and cleanliness is everything on a common rail system
