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 fueling 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) fueling, 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 fueling to support over 1200whp, regardless of fuel type.

Key Features:

• Twin-Pump Design: Boost-activated secondary pump ensures consistent fuel delivery under demanding conditions.
• High Power Support: Capable of handling 1200+whp, making it ideal for E85 and other high-performance applications.
• Complete Kit: Includes all necessary components for a seamless installation process.

Kit Contents:

1. Dual Pump Bucket Assembly
