Description
The Performance Fueling Solutions (PFS) S55 F8X Drop-In Brushless LPFP Upgrade is engineered for enthusiasts and racers who demand serious fuel delivery without sacrificing OEM reliability or simplicity. Built from a genuine factory BMW S55 fuel pump bucket and professionally modified to house a high-flow brushless fuel pump, this complete drop-in assembly provides the fueling capacity required for high-horsepower street and race builds while maintaining factory ECU control.
Unlike many aftermarket fuel system upgrades, the PFS Brushless LPFP requires no additional pumps, wiring kits, external controllers, or custom tuning. Simply remove your factory low-pressure fuel pump assembly, install the PFS unit, connect the factory electrical connector, and you're ready to go.
Every unit is professionally assembled, pre-wired, and extensively flow-tested in-house to ensure dependable performance before it leaves the shop.
