⚠️ Common Signs of Failure

• Diesel weeping or misting at a union nut
• Rough running or a misfire traced to one cylinder
• Chafed pipe where it rubs a neighbour or a bracket
• Cracked cone or a union nut that will not seal at torque
• Fuel smell in the engine space after running

🛠️ Service Notes

• Order by cylinder position — 421492 is cylinder 4 and 421494 is cylinder 6, and only a few grams separate the three
• Cap the pipe and the pump outlet while the pipe is off to keep dirt out of the fuel system
• Route the new pipe in its original clips so it cannot chafe against its neighbours
