Spool Performance FX-200 Upgraded High Pressure Fuel Pump System | G63 / G550 AMG [M177]

The Spool Performance FX-200 is a powerful upgrade for your Mercedes-AMG G63/G550 [M177] equipped with the M177 engine. Designed to significantly enhance fueling capacity, the FX-200 features a larger bore size than stock, delivering 80% more flow compared to the factory high-pressure fuel pump (HPFP). With this upgrade, your vehicle can support higher ethanol concentrations and bigger turbos, perfect for those seeking enhanced performance and efficiency.

Key Features:

• 80% More Flow:
  The FX-200 increases the flow capacity of your fuel system by 80% over stock, allowing for more fuel to reach your engine. This is essential for higher ethanol blends and bigger turbo setups, increasing overall performance potential.

• E85 Compatibility:
  The FX-200 is fully E85 compatible, making it ideal for high-performance builds that use ethanol as a fuel source. It is also designed to support higher-than-stock pressures up to 240bar, which boosts fuel injector output and reduces injection times, optimizing your fuel delivery system.

• Plug-and-Play Installation:
  This upgrade is plug-and-play, requiring no cutting or splicing of any kind. The system is easy to install, making it a hassle-free upgrade for anyone looking to enhance their vehicle’s fuel system.

• Bosch Spec 10-Micron Fuel Filter:
  The included Bosch spec 10-micron high-flow fuel filter provides superior filtration for your fuel system. It protects the high-pressure pump and injectors from debris, ensuring the longevity of your components without causing a noticeable pressure drop.

• Ethanol Content Monitor (Optional):
  The Ethanol Content Monitor (ECA) kit (optional) provides real-time monitoring of in-tank ethanol content and fuel temperature. The system includes a mobile app that uses BLE 4.0 technology, allowing you to monitor your fuel system via your mobile device for the most accurate readings.

• Complete Kit Includes:

  • 2 x FX-200 upgraded high-pressure fuel pumps

  • 1 x Ethanol Content Monitor (optional) with mobile app for real-time fuel data

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

  • Upgraded fuel lines made from braided steel nylon core, 100% E85 compatible

  • All necessary installation hardware for an easy and smooth setup

Why You Need It:

The stock HPFP in the M177 engine is limited in capacity, especially when you start tuning for higher power output. The FX-200 solves this limitation by providing 80% more flow, which allows you to run larger turbos and higher ethanol blends without worrying about fueling constraints. Whether you’re building a track car or tuning for more street power, the FX-200 ensures your engine gets the fuel it needs to maximize its potential.

Tune Requirements:

Custom tuning is required when installing the FX-200. Changes to the car’s calibration should be made before starting the vehicle with the upgraded pumps installed to avoid potential damage. Spool Performance provides calibration details to your existing tuner and can connect you with tuners experienced with this upgrade. Keep in mind, custom tunes are necessary to achieve optimal results for your specific vehicle setup and ambient conditions.

Low-Pressure Fueling:

Inadequate low-pressure fueling can severely affect the performance and durability of your high-pressure pumps and injectors. To avoid damaging the pump piston and bore, it is crucial to have a properly sized low-pressure fueling system in place. Make sure to plan for low-pressure fuel upgrades as needed to ensure the longevity and effectiveness of your high-pressure system.
