Spool Performance is excited to introduce our Stage 3 Low-Pressure Fuel Pump (LPFP) Kit for the S58 platform. This kit provides a comprehensive solution to low-side fuelling limitations by including everything needed to add a secondary boost-activated low-pressure pump.

As high-pressure fuel pumps continue to advance and support greater Direct Injection (DI) fuelling, stock low-pressure electric pumps have become a bottleneck when pursuing high horsepower—particularly with E85 fuel. Our Stage 3 LPFP Kit addresses this limitation with a twin-pump configuration, activating a secondary pump during boost onset. This setup nearly doubles the flow of the stock pump, providing sufficient fuelling to support over 1200whp, regardless of fuel type.
