Spool Performance Stage 3 Low Pressure Fuel Pump [B46/B48]

Unleash the full potential of your BMW B46 or B48 engine with the Spool Performance Stage 3 Low-Pressure Fuel Pump (LPFP)—a powerful, drop-in solution engineered for high-performance builds running ethanol (E85) or gasoline.

As performance tuning and upgraded high-pressure fuel pumps (HPFPs) allow for more aggressive direct injection (DI) fueling, the stock LPFP becomes the limiting factor—especially when pushing beyond stock power levels. That’s where Spool’s Stage 3 LPFP steps in.

Key Features:

Twin Pump System: Includes a primary pump for standard fueling and a secondary pump that activates under boost for nearly double the flow of the OEM pump.
Supports High Horsepower Builds: Designed to reliably support 1000+ wheel horsepower (whp) across all fuel types, including full E85.
Boost-Activated Secondary Pump: The second pump kicks in precisely when needed, maintaining fuel pressure under aggressive acceleration or high boost situations.
Direct Drop-In Fitment: No cutting, modifying, or wiring headaches—this kit is designed for plug-and-play compatibility with B46/B48 vehicles.
Optimized for Ethanol Use: Whether you’re running pump gas or full E85, the Stage 3 LPFP delivers the consistent flow and pressure your build demands.
