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

Description

Spool Performance is excited to introduce our Stage 3 Low-Pressure Fuel Pump Kit for the BMW S63 platform . Designed to eliminate low-side fueling limitations, this kit includes everything needed to add a secondary boost-activated low-pressure pump, ensuring consistent fuel delivery for high-horsepower builds. With high-pressure fuel pumps now supporting greater Direct Injection (DI) fueling , the stock low-pressure electric pumps have become a bottleneck when pushing for maximum performance, especially with E85 fuel . Our Stage 3 Low-Pressure Pump Kit addresses this challenge by featuring a twin-pump configuration. A secondary pump is activated during boost onset, doubling the flow capacity compared to the stock setup and supporting over 1200whp of low-pressure fueling, regardless of fuel type. Key Features: • Boost-activated Twin Pump Design: A second pump engages during boost for seamless high-flow fueling. • Supports High Power: Designed to handle 1200+whp , perfect for E85 and other high-demand setups. • Plug-and-Play Installation: Comes with all necessary components for straightforward integration. Kit Contents: • Dual Pump Bucket Assembly • Secondary Fuel Pump Activation Harness • Boost-activated Switch • Boost Reference Adapter • Hardware Pack
