Spool Performance FX-200 Upgraded High Pressure Fuel Pump System | [M157]

The FX-200 by Spool Performance is a complete high-pressure fuel pump upgrade engineered for the Mercedes-Benz M157 twin-turbo V8 engine. Designed to address the limitations of the stock fuel system, this kit offers a massive 80% increase in fuel flow capacity, enabling support for higher ethanol blends (E85 compatible) and larger turbocharger setups.

Key Features:

• High-flow upgraded fuel pumps with larger bore size
• Fully E85 compatible and plug-and-play installation — no cutting or splicing
• Supports fuel rail pressures up to 240 bar, enhancing injector output and reducing injection time
• Custom calibration required (Spool provides data for your tuner)

Why Choose the FX-200?
The factory high-pressure fuel pump on M157 engines is a well-known bottleneck when tuning for higher horsepower or running ethanol blends. The FX-200 eliminates this limitation by significantly increasing fueling capacity. Whether you're pushing your build with big turbos or increasing ethanol content, this system delivers the fuel volume and pressure you need.

Complete FX-200 Kit Includes:

• 2x Spool Performance FX-200 upgraded high-pressure fuel pumps
• Optional: 1x Ethanol Content Monitor (ECM) Kit with BLE 4.0 and mobile app integration
• 1x Bosch-spec 10-micron high-flow fuel filter
• High-quality braided steel E85-compatible fuel lines
• All necessary installation hardware

Spool 10-Micron Fuel Filter Unit:
This high-performance filter offers class-leading filtration without causing pressure drop in the low-pressure fuel system. It protects the upgraded HPFP and injectors from debris and contamination, making it highly recommended for long-term reliability.

Spool Ethanol Content Monitor Kit (Optional):
The ECM kit features real-time digital readout of in-tank ethanol content and fuel temperature via the Spool Performance mobile app. Powered by BLE 4.0 technology, it ensures reliable connectivity while allowing other Bluetooth devices to function normally.

Tune Calibration Required:
Calibration updates are mandatory before startup with the FX-200 installed to prevent damage and avoid voiding the warranty. Spool Performance does not offer tuning services but will provide all necessary calibration data and coordinate with your tuner to ensure optimal setup.

Low-Pressure Fueling Requirements:
To protect your upgraded HPFP and injectors, it’s essential to ensure your low-pressure fuel pump is capable of delivering sufficient volume. Fuel starvation at the low side can damage the FX-200 pumps and void warranty coverage. Please upgrade your low-pressure system accordingly if needed.
