Spool Performance FX-350 Upgraded High Pressure Fuel Pump System | AMG GT/GTS/GTC/GTR [M178]

The Spool Performance FX-350 high-pressure fuel pump upgrade is engineered for those looking to elevate their Mercedes AMG GT, GTS, GTC, or GTR [M178] to new levels of performance. Offering a 90% increase in fuel flow capacity compared to the stock fuel pump, the FX-350 is the perfect upgrade for drivers who demand more power, especially when running larger turbos or high-ethanol content fuels.

Key Features of the FX-350 Fuel Pump System:

Enhanced Fuel Flow & Pressure
The FX-350 is designed to deliver fuel at an impressive 35MPa, which is a substantial increase from the stock 25MPa. This increase in pressure allows for a 40% greater flow before maxing out the injectors, ensuring your engine gets the fuel it needs, even under extreme performance conditions. The FX-350 supports higher fuel requirements for larger turbos, higher ethanol concentrations, and aggressive performance tunes.

Improved Fuel Atomization
The higher fuel pressure offered by the FX-350 promotes better fuel atomization, which is crucial for achieving efficient and complete combustion in direct-injection (DI) engines. This results in increased power output, better fuel economy, and reduced emissions—critical for high-performance driving.

Ethanol Compatibility & Monitoring
The Spool Ethanol Content Monitor Kit (available option) allows you to easily monitor ethanol concentration and fuel temperature in real-time using the Spool Ethanol Analyzer App. The kit uses Bluetooth 4.0 technology for seamless integration with your smartphone, providing data without affecting your regular Bluetooth functions.

Complete Installation Kit
This fuel pump upgrade comes with everything you need for a hassle-free installation, including:

• 2 x FX-350 upgraded high-pressure fuel pumps

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

• Upgraded fuel lines (black nylon coated, braided steel PTFE core, 100% E85 compatible)

• All necessary install hardware

• Spool 10-micron filter unit to protect high-pressure pumps and injectors from debris

Why You Need the FX-350:

The stock HPFP on the M177 motors has limited capacity when it comes to supporting higher power levels. Whether you're tuning for bigger turbos or running higher ethanol content, the FX-350 will significantly enhance your fuel system’s ability to handle increased demands. This upgrade adds 90% more fuel flow, raising the fueling limits of your platform and enabling you to push your car’s performance to the next level.

Tune Changes and Calibration:

The FX-350 fuel pump system requires calibration changes to ensure proper function. It is essential to make these changes before starting the car with the pumps installed to avoid potential damage and avoid voiding the warranty. Spool Performance can assist with calibration details or connect you with experienced tuners familiar with the FX-350 setup.

Low-Pressure Fuel Pump Considerations:

Proper low-pressure fueling is crucial for the correct functioning and longevity of high-pressure pumps and injectors. Inadequate low-pressure fuel can damage the pump piston and bore, resulting in costly repairs and voiding warranties. Ensure your low-pressure system is upgraded as needed to support the FX-350’s performance.

Benefits:

• 90% more flow than stock fuel pumps, supporting larger turbos and higher ethanol blends

• 35MPa fuel pressure for more fuel and better atomization

• Free app for ethanol content monitoring and fuel temperature readings

• Bosch spec fuel filter and high-quality fuel lines

• Seamless integration with existing fuel systems

• Lifetime warranty for peace of mind

Unlock Your Vehicle’s Full Potential with the Spool FX-350 High-Pressure Fuel Pump System—the ideal solution for AMG GT/GTS/GTC/GTR [M178] owners looking to push their performance to new heights.
