## ⚠️ Common Signs of Failure

-   Diesel leakage at either union
-   Cylinder-specific misfire or low power
-   Pipe cracking from vibration or incorrect clamping
-   Fuel spray or injection-pressure loss

## 🛠️ Service Notes

-   Work scrupulously clean — cap or plug every opening as it is broken and let nothing enter the pipe or its unions, because a single particle carried into the injection system will damage what it reaches
-   Offer the pipe up so the union faces meet squarely and fit it dry and without strain; never bend, straighten or re-form a delivery pipe to make it reach
-   Renew rather than reuse a pipe where the procedure for your engine calls for it — the sealing cone work-hardens in service and often will not seal a second time
-   Tighten the unions with the correct socket to the figure in the workshop manual for your engine; under-tightening leaks and over-tightening deforms and cracks the sealing cone
-   Never slacken a union to bleed or check a system that is running or still pressurised, and look for leaks only with the engine stopped and the area wiped dry
