🔌 Function

Carries surplus fuel back from the injection system to the tank so the circuit does not build pressure.

⚠️ Common Signs of Failure

• Fuel weeping at a union or along the line
• Diesel smell in the engine bay
• Line kinked, chafed or split
• Hard starting or hunting from air entering the circuit
• Bore restricted, so pressure builds in the return path

🛠️ Service Notes

• Confirm you need the late type — the early pattern is a different part
• Fit new sealing washers at the unions, bleed the system and check for weeps at working pressure

📦 Condition

• Supplied in original or equivalent packaging
