Stage 2 Low-Pressure Bucketed Fuel Pump Kit

The Precision Raceworks Low-Pressure Bucketed Fuel Pump Kit - Stage 2 is engineered to significantly increase fuel delivery for BMW vehicles aiming for higher power output. It features a genuine Walbro 450 (F90000274) fuel pump, designed to support up to approximately 575 wheel horsepower on 93 octane pump gas and up to 500 wheel horsepower when running 100% E85. This kit is presented as a true plug-and-play solution that can be installed in a home garage without requiring the sender's original fuel pump. It includes all necessary components for assembly, which aims to prevent shipping delays, potential damage to the stock fuel pump housing, and reduce assembly costs. The design also simplifies installation by eliminating guesswork regarding O-ring engagement and sealing, and avoids risks associated with tightening clamps that could damage nearby plastic components. While bucketless fuel pumps offer improved flow over designs retaining a venturi, they have specific operational limitations. These pumps should not be operated with less than a 1/4 tank of fuel and are not recommended for road course racing. If road course or drag racing is not planned, and the user is diligent about maintaining a minimum fuel level during spirited driving, this bucketless pump can be a more cost-effective option. Some European Spec BMW vehicles may require the reuse of the original top hat due to variations in emissions requirements. Additionally, this product is not for sale or use in the state of California on any pollution-controlled vehicle, as per the California Air Resources Board regulations.
