⚠️ 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

• Cylinder position is the only thing separating these pipes — 421493 is cylinder 5 and 421494 is cylinder 6, and their weights are within a few grams of each other
• Never bend a high pressure pipe to make it fit, and never reuse one with a damaged cone
• Tighten the union nuts to the specified figure and bleed the system before starting
