The Burger Motorsports (BMS) Stage 3 Low Pressure Fuel Pump (LPFP) Upgrade Kit is engineered for high-horsepower BMW S58 and Gen2 B58 applications requiring significantly increased fuel delivery. Designed to support demanding performance builds, this advanced fuel system upgrade incorporates an additional Walbro fuel pump to provide the fuel volume necessary for aggressive tuning, upgraded turbochargers, ethanol blends, and high-boost applications.

The Stage 3 LPFP Upgrade Kit is capable of supporting up to 900 wheel horsepower when equipped with the Walbro 450 pump and up to 1100 wheel horsepower when equipped with the Walbro 525 pump, making it an ideal solution for enthusiasts pushing their BMW platform beyond factory fuel system limitations.

Unlike many competing systems, this innovative LPFP upgrade maintains full functionality of the factory direct injection fuel filter and low-pressure fuel regulator. Retaining these critical factory components helps protect expensive direct injection injectors from contamination while reducing the risk of excessive fuel pressure that can damage factory plastic fuel lines.

Designed as a complete do-it-yourself upgrade, the kit can typically be installed in less than one hour using standard tools. The secondary fuel pump can be activated through a variety of control methods, providing flexibility for different performance setups.
