⚙️ Key Features

🔌 Function

Collects the small spill flow from the injectors and returns it to the fuel circuit.

⚠️ Common Signs of Failure

• Diesel smell or wet film around the injector heads
• Fuel weeping from the small unions between injectors
• Air in the fuel circuit and hard starting
• Perished or split sealing washers at the pipe joints
• Pipe body cracked at a bend or a brazed joint

🛠️ Service Notes

• The sealing washers at each injector union are single-use — fit new ones with the pipe
• Because this number now covers what were two earlier pipes, compare the new pipe against the old routing before disturbing the injectors
