🔌 Function

Collects the small amount of fuel that leaks past each injector and returns it, so it cannot build pressure or find its way into the oil.

⚠️ Common Signs of Failure

• Diesel smell in the engine bay, with wet unions
• Air drawn into the fuel system, giving hard starting
• Pipe hardened, cracked or split at the connections
• Sealing washers flattened and weeping
• Fuel level rising in the sump from a leaking return

🛠️ Service Notes

• Renew the sealing washers at every leak-off connection, as they are single-use
• Check whether the engine falls before serial number 5102178578C, since pipe 3812452 covers the earlier build
• Never plug or bypass a leak-off line
