Collects injector leakage fuel and returns it to the low-pressure side of the common-rail system.

## ⚠️ Common Signs of Failure

-   Diesel smell and a wet trail along the top of the engine
-   Hard starting, particularly after the engine has stood overnight
-   Air drawn into the fuel system, giving rough running and hunting
-   Line found hardened, cracked at the connectors or split at a bend
-   Connector seals perished so the pipe pulls off its spigot by hand

## 🛠️ Service Notes

-   Renew all disturbed sealing washers, O-rings, grommets and hose clamps.
-   Confirm the pipe is naturally aligned before tightening; do not pull it into position with the fasteners.
