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.
• Twin-pump configuration: Ensures consistent fuel delivery under demanding conditions.
• E85 compatibility: Optimized for high-performance applications.

 

Kit Includes:

1- Fully Built Drop-in LPFP assembly

1- Secondary Fuel Pump Activation Harness

1- 10psi Hobbs Switch (If "Spool Wiring Harness" option selected)
