This is a Genuine Nissan common rail injector fuel rail, designed as a direct replacement for specific Nissan Navara D22 and D40 models fitted with the YD25DDTI engine. Located on the right-hand (driver's side) of the engine block and mounted horizontally beneath the air intake manifold, its job is to store and distribute high-pressure fuel evenly to the injectors.
This is a complete, ready-to-install assembly that includes both the fuel pressure switch and the pressure relief valve, which are common failure points in the YD25 fuel system. Replacement is often required to resolve persistent fuel pressure fault codes like P0087 (Fuel Rail Pressure Too Low) or P0088 (Fuel Rail Pressure Too High), or in cases of severe fuel system contamination. As the pressure switch cannot be purchased separately from Nissan, this complete rail is the only genuine solution for a failed switch.
This is a moderate-difficulty job (3/5) that demands extreme cleanliness to prevent fuel system contamination. You will need the right tools, including nut spanners (flare nut wrenches) for the high-pressure lines, a socket set, and a calibrated torque wrench to prevent leaks. It's also wise to have clean caps ready to seal any open lines immediately.
Please check vehicle fitment to confirm compatibility with your vehicle. Please contact us with your VIN details if you require further assistance to confirm fitment.
