Spool Performance FX-170 Upgraded High Pressure Fuel Pump System | E63 AMG [M177]

The Spool FX-170 Upgraded High-Pressure Fuel Pump System is an essential upgrade for performance enthusiasts seeking to enhance the fueling capacity of their Mercedes-Benz E63 AMG [M177]. Designed to meet the demands of high-output builds, this system delivers a 50% increase in fuel flow over the stock pump, allowing you to run higher ethanol concentrations and support larger turbochargers, resulting in significant performance gains.

Fitment:

• Vehicle: Mercedes-Benz E63 AMG

• Engine: M177 (4.0L V8 Twin-Turbo)

Key Features:

• 50% Increased Flow: The FX-170 fuel pump is engineered with a larger bore size than the factory pump, providing 50% more fuel flow. This upgrade is vital for those running high-performance turbo setups or tuning their vehicle with higher ethanol blends like E85.

• E85 Compatibility: Designed with full E85 compatibility in mind, the FX-170 offers a seamless transition to higher ethanol concentrations, boosting both performance and efficiency. It requires no cutting or splicing, offering a simple plug-and-play installation.

• Complete Upgrade Kit: The FX-170 kit provides everything needed for a full fuel system upgrade, including:

  • 2 x FX-170 high-pressure fuel pumps

  • 1 x Ethanol Content Monitor (optional) with mobile app integration

  • 1 x Bosch spec 10-micron high-flow fuel filter

  • Braided steel nylon-core fuel lines, 100% E85 compatible

  • All necessary hardware for a hassle-free installation

• Spool 10-Micron Filter: The included Bosch spec 10-micron high-flow fuel filter ensures maximum filtration with no noticeable pressure drop, providing your high-pressure fuel pump and injectors with protection from debris and contaminants.

• Ethanol Content Monitor (Optional): The optional Spool Ethanol Content Monitor allows you to track ethanol content and fuel temperature in real-time using the mobile app, utilizing Bluetooth Low Energy (BLE 4.0) technology. The module also features a 0-5V output for flex-fuel capability, making it a versatile addition for future upgrades.

• Tune Calibration Required: To achieve the full potential of the FX-170, custom tuning and calibration adjustments are necessary. Calibration should be completed before engine startup to avoid damage. Spool Performance can provide your tuner with the necessary calibration details, or help you connect with experts familiar with the FX-170 setup.

• Low-Pressure Fueling Considerations: Proper low-pressure fueling is essential to maintain the durability and function of the high-pressure pumps and injectors. If low-pressure fueling is insufficient, it may result in damage that voids warranties. Be sure to upgrade your low-pressure fuel system if necessary.

Why Upgrade?

The stock high-pressure fuel pump (HPFP) on the M177 engine is limited in flow capacity when running high-output turbo builds or ethanol-based fuels. The Spool FX-170 addresses this by providing the necessary fuel flow to support more aggressive tuning, including higher ethanol blends and larger turbochargers, making it a critical upgrade for any performance-driven E63 AMG.
