-   Must not be bent, reshaped or reused if damaged

## 🔌 Function

The pipe delivers rail pressure to injector 6 while maintaining the precise sealing and routing required by the common-rail system.

## ⚠️ Common Signs of Failure

-   Diesel leakage or high-pressure fuel spray
-   Cylinder 6 misfire

## 🛠️ Service Notes

-   Work clean: cap or plug every open union and injector as soon as it is disconnected, and fit the new pipe straight from its packaging — dirt introduced at a fuel joint is the most common cause of trouble afterwards
-   Offer the pipe up so it lines up on both unions without strain, and never bend, twist or reshape a pipe to make it fit; a pipe that has been sprung into place fatigues and cracks in service
-   High-pressure delivery pipes are treated as single-use in workshop practice — the union faces seal by deforming, so refit new pipes rather than reusing them, and tighten to the figure and sequence in the workshop manual for your engine
-   Refit all original support clips and brackets in their proper positions so the pipe cannot chafe or vibrate against surrounding parts
-   Bleed the system, then check the joints for leaks with the engine running and again once warm — never search for a diesel leak by hand, since fuel at injection pressure will penetrate skin
