Maintain reliable high-pressure diesel fuel delivery with this Genuine Nissan No.4 Injector Pipe, designed specifically for Nissan Patrol GU Y61 models fitted with the ZD30Di direct-injection diesel engine. This OEM high-pressure injector pipe connects the injection pump directly to the No.4 fuel injector, helping deliver precisely metered diesel fuel for reliable combustion and engine performance.

Over time, injector pipes can develop metal fatigue, cracks, leaks, or damage due to constant exposure to high fuel pressure, engine vibration, heat, and general wear. A leaking or damaged injector pipe can contribute to hard starting, rough idling, loss of engine power, and excessive black smoke. Replacing a worn or damaged pipe helps restore reliable fuel delivery and reduces the risk associated with high-pressure diesel fuel leaks.

Manufactured to Genuine Nissan specifications, this No.4 injector pipe features precisely formed bends and factory-flared ends for correct fitment and reliable sealing. It is an ideal replacement when servicing the fuel injection system or replacing a worn, fatigued, or damaged factory injector pipe.
