Spool Stage 3 Low Pressure Fuel Pump - DIY Kit [S63 | F90 M5]

Description

Spool Performance is excited to introduce our Stage 3 Low-Pressure Fuel Pump DIY Kit for the BMW F90 M5 S63 , designed for enthusiasts who prefer a hands-on solution to their fueling challenges. As high-pressure fuel pumps now support greater Direct Injection (DI) fueling , the stock low-pressure electric pumps have become a limiting factor when pursuing high horsepower—especially with E85 fuel . The DIY Kit offers comparable performance to plug-and-play kits at a fraction of the cost. It includes all the components needed to add a secondary boost-activated low-pressure pump, effectively doubling the flow capacity of the stock setup. This ensures more than enough fueling to support over 1200whp , regardless of fuel type. Key Features: • Boost-activated Twin Pump Design: A second pump activates during boost to meet high-demand fueling needs. • Cost-effective DIY Solution: Delivers the same performance as pre-assembled kits at a reduced cost. • Supports High Power: Perfect for builds exceeding 1200whp , ideal for E85 applications. • User-friendly Assembly: Comes with detailed instructions for an easy installation process. Kit Contents: • Secondary Fuel Pump Assembly • Secondary Fuel Pump Activation Harness • Boost-activated Switch • Boost Reference Adapter • Hardware Pack
