🔌 Function

Returns leak-off fuel from the injectors to the fuel system instead of letting it collect on the engine.

⚠️ Common Signs of Failure

• Diesel smell and wet streaks along the line or at the injectors
• Line cracked or chafed through
• Union nuts weeping or seized
• Hard starting or rough running from air drawn into the return
• Fuel pooling in the valve cover area

🛠️ Service Notes

• Because the published build reference is incomplete, confirm the engine number and compare against the line fitted
• Renew the sealing washers at every union - leaking diesel on a hot engine is a fire risk, so do not reuse them
