Spool Performance FX-350 Upgraded High Pressure Fuel Pump System | GLE63 AMG [M177]

The Spool Performance FX-350 Upgraded High-Pressure Fuel Pump System is designed specifically for the Mercedes GLE63 AMG [M177] to meet the demands of high-performance applications. With enhanced pressure and flow, the FX-350 takes fuel delivery to the next level, offering 90% more flow compared to stock pumps. This upgrade is essential for enthusiasts aiming to push the limits of their performance engines, especially when running larger turbos or higher ethanol concentrations.

Fitment:

• Vehicle: Mercedes-Benz GLE63 AMG

• Engine: M177 (4.0L V8 Twin-Turbo)

• Application: High-performance fueling for increased output and tuning, ideal for upgraded turbos and ethanol blends.

Key Features:

• Enhanced Pressure & Flow:
  The FX-350 operates at a remarkable 35Mpa, significantly higher than the FX-200’s 25Mpa. This increase in pressure results in a 40% greater fuel flow through the injectors, ensuring that the engine receives the proper amount of fuel to match upgraded turbo setups and higher ethanol concentrations. This means more fuel for better combustion, enhancing overall engine performance.

• Improved Fuel Atomization:
  The increased pressure of the FX-350 allows for better atomization of fuel, improving how the fuel mixes with air in the combustion chamber. This results in more efficient combustion, which translates into higher power output, better fuel economy, and reduced emissions.

• Better Performance & Efficiency:
  The FX-350 high-pressure fuel pump provides the necessary fueling for modified GLE63 AMG engines, supporting larger turbos or higher ethanol blends while maximizing engine output. With 90% more flow than stock pumps, it effectively raises the fueling limits of the M177 motor platform.

• Complete Fuel System Upgrade:
  The kit includes 2 x FX-350 fuel pumps, a Bosch spec 10-micron high-flow fuel filter, upgraded fuel lines, and all the necessary installation hardware to ensure smooth operation and long-term durability.

• Ethanol Content Monitor (Optional):
  The Spool Ethanol Content Monitor Kit provides a digital readout of in-tank ethanol content and fuel temperature. Paired with the mobile app and Bluetooth 4.0 technology, you can monitor your fuel’s ethanol concentration in real-time. This feature helps you ensure that your fuel system is operating optimally when using higher ethanol content blends.

• 10-Micron Fuel Filter Unit:
  The Spool 10-micron filter offers superior filtration without causing noticeable pressure drops in the low-side fuel system. It keeps the high-pressure pump and injectors safe from debris, which is crucial for performance and reliability.

• Tuning & Calibration Requirements:
  The upgraded FX-350 pumps require calibration changes to optimize performance. Custom tuning is required to achieve the best results based on your vehicle setup and conditions. Spool Performance provides tuning guidance and can help connect you with tuners experienced with this upgrade.

• Low-Pressure Fuel Pump Considerations:
  Ensuring proper low-pressure fueling is critical for maintaining the integrity and durability of the high-pressure system. Inadequate low-pressure fueling can damage the pump piston and bore. Spool Performance advises ensuring your fuel system build includes proper low-pressure upgrades when necessary.

Kit Includes:

• 2 x FX-350 Upgraded High-Pressure Fuel Pumps

• 1 x Bosch Spec 10-Micron High-Flow Fuel Filter

• Upgraded Fuel Lines

• Spool Ethanol Content Monitor Kit (Optional)

• All necessary installation hardware
