Spool FX-200 High-Pressure Fuel Pump

The Spool FX-200 Upgraded High Pressure Pump is engineered to replace the stock unit in BMW N20 and N26 engines, offering a significant increase in fuel flow capacity. Featuring a larger bore size, it delivers approximately double the flow of the OEM pump, directly addressing the fueling limitations encountered when tuning for higher performance. This upgraded pump is fully compatible with E85 fuel and is designed for a plug-and-play installation, eliminating the need for any cutting or splicing of the existing fuel lines or wiring. The increased flow capability allows for higher ethanol concentrations and supports the demands of larger turbocharger upgrades, making it essential for those pushing the performance envelope of their N20/N26 powerplant. It is crucial to note that the installation of the FX-200 requires calibration changes. These adjustments must be applied before starting the engine with the new pump installed to prevent potential damage and avoid voiding the warranty. Spool Performance can provide calibration details to your tuner or assist in connecting you with tuners experienced with this pump. Custom tuning is mandatory to achieve the maximum potential of this upgraded pump and is specific to your vehicle's setup and environmental conditions. Furthermore, proper low-pressure fueling is paramount for the durability and correct functioning of high-pressure fuel systems and injectors. Inadequate low-pressure fuel delivery can lead to damage to the pump piston and bore, which are lubricated by controlled fuel leakage. Such damage resulting from low-pressure starvation is detectable and will void the warranty. It is essential to plan for necessary low-pressure fuel system upgrades alongside the HPFP installation.
