## 🔌 Function

Holds the fuel rail and its brackets to the intake manifold so the rail and injectors stay located against fuel pressure and vibration.

## ⚠️ Common Signs of Failure

-   Fuel smell or a damp patch around the fuel rail
-   Rail or injector free to rock by hand
-   Screw found loose or missing
-   Head recess damaged so a tool slips
-   Thread damage in the manifold boss on removal

## 🛠️ Service Notes

-   Depressurise the fuel system before disturbing the rail, and check the injector seals for leakage while the rail is off
-   It is a small fastener into a light alloy boss, so a stripped boss rather than a stretched screw is the usual reason the joint will not hold
