Spool Performance GLS63 AMG [M177] Spool FX-200 Upgraded High Pressure Pump Kit

Introducing the Spool Performance FX-200, a high-pressure fuel pump designed to significantly enhance the performance of your Mercedes-AMG GLS63 M177. Building on advanced engineering, the FX-200 is crafted to support increased fuel demands and optimize your engine's output.

What is the FX-200?

The FX-200 is an upgraded high-pressure fuel pump that delivers superior performance over stock pumps:

• Enhanced Flow: Featuring a larger bore size than the stock pump, the FX-200 provides approximately 80% more flow. This increased flow rate supports higher ethanol concentrations and larger turbos.

• E85 Compatibility: Fully compatible with E85, the FX-200 offers a plug-and-play installation with no cutting or splicing required. It can handle pressures up to 240bar, enhancing fuel injector output and reducing injection time.

Why do you need it?

The stock high-pressure fuel pump (HPFP) in the M177 motors has limitations that can restrict tuning and performance:

• Increased Flow Capacity: The FX-200 boosts flow by 80%, which helps overcome the limitations of the stock pump. This allows for running bigger turbos and higher ethanol blends, optimizing engine performance.

What does the kit include?

• 2 x FX-200 Upgraded High-Pressure Fuel Pumps
• 1 x Ethanol Content Monitor Kit (if selected) with mobile apps
• 1 x Bosch Spec 10-Micron High-Flow Fuel Filter
• Upgraded Fuel Lines and all necessary installation hardware

Spool 10-Micron Filter Unit

The 10-micron filter unit offers:

• Superior Filtration: Provides the best filtration available for the M177 market, protecting the high-pressure pump and injectors from debris without causing noticeable pressure drops.

Spool Ethanol Content Monitor

The Spool Ethanol Content Monitor (ECA) features:

• Digital Readout: Displays in-tank ethanol content and fuel temperature.
• Mobile App: Includes the SPOOL Ethanol Content Analyzer app for real-time monitoring.
• BLE 4.0 Technology: Enables connectivity with standard Bluetooth devices.
• E85-Compatible Fuel Lines: Braided steel nylon core lines included in the kit.

Are tune changes required?

Yes, calibration changes are necessary to accommodate the upgraded pumps:

• Calibration Requirements: Apply calibration changes before starting the car to avoid potential damage and warranty issues. Spool Performance can assist in providing calibration details to your tuner or help connect you with experienced tuners.

Low Pressure Fuel Pump Upgrade

Proper low-pressure fueling is critical for the durability of high-pressure pumps and injectors in a direct-injection system:

• Importance of Low Pressure Fueling: Inadequate low-pressure fueling can lead to pump piston and bore damage, which may void warranties. Ensure your fuel system build includes appropriate low-pressure upgrades.
