⚙️ Key Features

• High-pressure fuel pipe for injector 3
• 0.175 kg
• Listed for three TAD series engine applications
• Each pipe is formed for one cylinder, so the injector position is the selection detail
• Supersedes 21739047

🔌 Function

Carries fuel at injection pressure from the rail or pump to injector 3, its bends and length fixed by the run between the two.

⚠️ Common Signs of Failure

• Diesel smell or a wet film around the pipe run
• Knocking or a misfire on one cylinder
• Hard starting, or a drop in power
• Cone end found fretted, ring-marked or cracked on strip-down
• Chafe mark where the pipe has touched a neighbouring pipe or bracket

🛠️ Service Notes

• High-pressure pipes are single-use once the cone has bedded - do not refit a pipe that has been removed
• Refit the clamps and spacers exactly as they were set; an unsupported pipe fatigues and cracks at the cone
• Tighten the unions to the figure in the workshop manual - overtightening deforms the cone and causes the leak it was meant to cure
