🔧 Product Description

From the Fuel System group, it weighs 0.197 kg and is listed for 2 applications across the KAD and KAMD series.

⚠️ Common Signs of Failure

• Diesel weeping or misting at the cone unions
• Smell of fuel around the pump and injector
• Rough running or a misfire traced to one cylinder
• Chafe marks or a flattened section where the pipe touches something
• Cracking at the shoulder of a union nut

🛠️ Service Notes

• Pipes 860843, 860844 and 860846 cover cylinders 3, 4 and 6 in this run, and each cylinder takes its own pipe, so order by cylinder number
• Never bend a delivery pipe to make it fit; a reshaped pipe cracks at the union
• Never crack a union with the engine running, as injection pressures can penetrate skin
