⚙️ Key Features

• For engines from serial number 5312147988 onwards
• 2.331 kg
• Listed for two TAD series applications
• Supersedes 20798896
• Holds fuel at injection pressure, so it is a high pressure component

🔌 Function

Stores fuel at injection pressure and distributes it to the injectors, damping the pressure pulses each injection event creates.

⚠️ Common Signs of Failure

• Hard starting or a loss of power with rail pressure fault codes stored
• Diesel smell in the engine space with no obvious pool
• Wet streaks or a varnished trail below a union on the rail
• Engine derating or cutting out under load
• Corrosion or damaged threads at a union found on inspection

🛠️ Service Notes

• The serial break governs fitment - confirm the engine number falls on or after 5312147988 before ordering
• Depressurise the system and let it stand before opening any union, and work clean, since fuel at injection pressure will penetrate skin
• Renew the high pressure pipes rather than refitting them - a reused pipe rarely re-seals on its cone
