Spool Stage 3 Low Pressure Fuel Pump (Built Bucket) - F-Series Gen 1 B58

Spool Performance is proud to introduce the drop-in Stage 3 Low-Pressure Fuel Pump (LPFP) upgrade for the BMW Gen1 B58 platform . As high-pressure fuel pumps have advanced to support greater Direct Injection (DI) fueling, we've identified the stock low-pressure electric fuel pumps, which deliver fuel from the tank to the high-pressure pumps, as a critical bottleneck when pursuing high horsepower—especially with E85 fuel . Our Stage 3 LPFP kit is the ultimate solution. Featuring a twin-pump configuration, this innovative design activates a secondary pump during boost onset, effectively doubling the flow capacity compared to the stock pump. With this upgrade, you'll achieve sufficient low-pressure fueling to support over 1000whp , regardless of fuel type. Key benefits of the Spool Performance Stage 3 LPFP: Drop-in design: Simplifies installation for seamless integration.

Fits: BMW F-series B58: M140i, M240i (F22), 340i (F30), 440i (F32)
