• 6 applications across the D series range
• Supersedes 30622085, formerly listed as a distribution pipe
• Fuel System group

🔌 Function

Holds fuel at injection pressure in a shared accumulator, so every injector draws from the same steady supply independently of the pump's delivery pulses.

⚠️ Common Signs of Failure

• Diesel weep or a wet film around the rail unions
• A strong fuel smell in the engine space
• Rough running, misfire or a rail pressure fault recorded
• Hard starting, or power falling away under sustained load
• Corroded union bosses, damaged sealing cones or a cracked boss found on inspection

🛠️ Service Notes

• Never slacken a union with the engine running or the system still pressurised - let the rail depressurise first
• Renew the high-pressure pipes rather than re-using them; their sealing cones are formed on first tightening
• Work clean - a single particle entering an open rail will damage the injectors it feeds
