Carries fuel at injection pressure from the injection pump to the injector for its cylinder, with the pipe length and bend set to give the correct delivery timing.

⚠️ Common Signs of Failure

• Fuel weeping or spraying at a pipe union
• Misfire, knock or rough running on that cylinder
• Pipe chafed, kinked or cracked near a union nut
• Union nut or the cone seat damaged, so the joint will not seal
• Diesel smell and fuel staining down the side of the engine

🛠️ Service Notes

• Order by the cylinder number, since the five pipes are almost identical in weight
• Confirm the engine serial is 2071080911 or below before ordering
• Never slacken a delivery pipe with the engine running, as fuel at injection pressure will penetrate skin, and refit to the specified torque with the pipe clips in place
