Spool FX-200 Upgraded High Pressure Pump Kit [M157]

The Spool FX-200 High Pressure Fuel Pump Kit is designed for Mercedes M157 engines, delivering a significant boost in fuel flow and pressure. This upgrade is essential for tuning and enhancing performance, supporting higher ethanol blends and larger turbos with ease.

What is the FX-200?

The FX-200 is an advanced high-pressure fuel pump featuring a larger bore size compared to stock, which translates to approximately 80% more flow. This pump is fully E85 compatible and offers a plug-and-play installation with no need for cutting or splicing. It supports fuel pressures up to 240 bar, improving fuel injector output and reducing injection time, making it ideal for high-performance applications.

Why You Need It

The stock high-pressure fuel pump (HPFP) on M157 motors has limited capacity, especially when increasing engine output. The FX-200 addresses this by adding 80% more flow, which raises the fueling limits, enabling you to run larger turbos and higher ethanol concentrations effectively.

What Does the Kit Include?

• 2 x FX-200 Upgraded High-Pressure Fuel Pumps
• 1 x Ethanol Content Monitor Kit (if option selected) with mobile app
• 1 x Bosch Spec 10-Micron High Flow Fuel Filter
• Upgraded Fuel Lines and All Necessary Install Hardware

Spool 10-Micron Filter Unit

The 10-micron filter unit provides the best filtration available for the Mercedes market, ensuring no noticeable pressure drop in the low-side fuel system. It protects the high-pressure pump and injectors from debris, which is crucial for maintaining performance and longevity.

Spool Ethanol Content Monitor

The ECA kit features a digital readout of in-tank ethanol content and fuel temperature. It includes the Spool Ethanol Content Analyzer app for mobile devices and delivers data via BLE 4.0 technology, ensuring minimal battery usage and compatibility with your Bluetooth devices. The kit also includes braided steel nylon core fuel lines, which are 100% E85 compatible.

Are Tune Changes Required?

Yes, calibration changes are necessary when installing the upgraded pumps. These changes should be made before starting the vehicle to prevent potential damage and warranty issues. Spool Performance can provide calibration details to your existing tuner or assist in connecting you with experienced tuners. Custom tuning is required to maximize the performance of the upgraded pump setup for your specific vehicle and conditions.

Low Pressure Fuel Pump Upgrade

Adequate low-pressure fueling is critical for the proper functioning and durability of high-pressure pumps and injectors in direct injection systems. Insufficient low-pressure fueling can lead to pump piston and bore damage due to inadequate lubrication. Planning your fuel system build with appropriate low-pressure upgrades is essential to avoid damage and warranty issues.
