Spool - Stage 3 Low Pressure Fuel Pump Kit || F06/F1X (S63)

Empire Autowerx Stage 3 LPFP Upgrade – BMW S63 Platform

High-Flow Dual Pump Fuel System – Supports Over 1200WHP on E85

If you're chasing four-digit horsepower from your S63-powered BMW, don’t overlook your low-pressure fuel system. While high-pressure pumps now handle direct injection with ease, the factory in-tank electric pump becomes a serious bottleneck, especially on E85.

Our Stage 3 LPFP (Low-Pressure Fuel Pump) upgrade solves this with a dual pump configuration — activated under boost via Hobbs switch. It delivers nearly double the flow of stock, giving you the fueling capacity to support 1200+ wheel horsepower, no matter your fuel type.
