BMW X3 N47 Engine High Pressure Pump – Reliable Fuel Delivery Replacement

Maintain strong diesel performance with this BMW X3 N47 engine high pressure pump, designed for X3 models equipped with the N47 2.0D engine. The high-pressure pump plays a critical role in the common-rail fuel system. It delivers precise pressure to the injectors, ensuring clean combustion, strong torque, and smooth acceleration. When it begins to fail, the vehicle may become difficult to start, lose power, surge, or trigger fuel pressure fault codes. Replacing the pump restores stability across the entire fuel system.

This unit follows the correct factory layout, so technicians can install it easily. The fuel lines, sensor points, and electrical connections match the original positions, which helps maintain a clean and accurate fit. Once installed, the pump supplies consistent pressure, even during heavy throttle use or high-speed driving.

The durable internal components are designed to resist diesel contamination, heat, and long-term wear. Additionally, the pump supports stable idling, improved throttle response, and reduced smoke under acceleration. As a result, the engine performs more efficiently and maintains its reliability on both short trips and long-distance travel.

This pump is ideal for drivers experiencing low fuel pressure, injector faults, stalling, diesel knock, or loss of power. Many N47 owners replace the pump during fuel system overhauls or when repairing vehicles affected by poor-quality diesel. Installing a proper high-pressure pump protects the injectors, fuel rail, and overall engine health.
