This is a quality aftermarket replacement injector pipe for the number two cylinder, designed specifically for Nissan Navara D22, D40, and Pathfinder R51 models fitted with the YD25 engine. It serves as a direct-fit replacement for a damaged or leaking original pipe.

Located on the top of the engine, this high-pressure line connects the common fuel rail to the No. 2 fuel injector (the second cylinder closest to the radiator). Its job is to transport high-pressure diesel fuel reliably for combustion. Each of the four injector pipes is unique, so it is crucial to select the correct one for the cylinder you are replacing.

Due to constant engine vibration and high-pressure fuel cycles, these pipes can develop fatigue cracks over time, leading to fuel leaks, a strong diesel smell, and poor engine performance. An inferior quality pipe is a serious fire risk. For a secure, leak-free seal, it is highly recommended to replace this pipe any time it is removed, as it is considered a single-use component.

Product Features

• Direct-Fit Replacement: Engineered to match the original No. 1 injector pipe for correct fitment, alignment, and a secure, high-pressure seal.

• Durable Construction: Made from high-grade steel tubing to withstand extreme fuel pressures and engine vibration, meeting or exceeding OEM standards for reliability.

• Restores Fuel System Integrity: Eliminates dangerous fuel leaks and corrects performance issues such as rough idling, engine hesitation, and fuel starvation.

• Critical Safety Component: Using a quality replacement pipe prevents the serious fire risks associated with cracked or poorly manufactured high-pressure fuel lines.

Installation Notes

Installation is a moderate workshop job that requires care to avoid contaminating the fuel system and ensuring high-pressure fittings are torqued correctly. While replacing this pipe, it is strongly recommended to inspect the other three injector pipes for any signs of wear, corrosion, or cracking.
