Spool Performance FX-170 Upgraded High Pressure Fuel Pump System | G63 / G550 AMG [M177]

Maximize the fueling capability of your Mercedes-AMG G63 [M177] with the Spool FX-170 High Pressure Fuel Pump Upgrade. Specifically designed for high-performance builds and E85 fueling, the FX-170 delivers a substantial 50% increase in flow over the stock pump, making it the perfect choice for vehicles running bigger turbos, higher ethanol blends, or pushing their engine to its limits. This plug-and-play upgrade ensures you get more fuel flow without the need for cutting or splicing, making it an easy and reliable solution to boost your fueling capacity.

Key Features:

• 50% More Flow than Stock Pumps:
  The FX-170 high-pressure fuel pump features a larger bore size than the stock pump, offering 50% more flow, making it ideal for supporting more aggressive performance builds. This upgrade is designed to handle larger turbos and higher ethanol concentrations, unlocking more power potential in your vehicle.

• E85 Compatibility:
  The FX-170 is fully E85 compatible, ensuring that you can run higher ethanol concentration blends without worrying about fueling limitations. This compatibility allows your vehicle to take advantage of the power and efficiency benefits that E85 provides.

• Plug-and-Play Installation:
  Installation is simple and straightforward with the FX-170, as it is completely plug-and-play. No cutting or splicing is required, making this upgrade a hassle-free solution that can be easily integrated into your G63 fuel system.

• Supports High-Performance Builds:
  The increased flow capacity of the FX-170 allows for greater fuel delivery, which is critical when running larger turbos or building high-horsepower engines. If you're targeting higher power outputs or planning to run E85 or other ethanol-based fuels, this upgrade will provide the fueling support you need.

• Enhanced Protection with Spool 10-Micron Filter:
  The included Bosch-spec 10-micron high-flow filter ensures the safety of your fuel system by keeping contaminants out of the high-pressure pump and injectors. The filter boasts top-tier filtration without causing noticeable pressure drop, making it a crucial component of your high-performance fueling setup.

• Spool Ethanol Content Monitor:
  The Ethanol Content Analyzer (ECA) gives you real-time digital readouts of in-tank ethanol content and fuel temperature. The app connects via Bluetooth 4.0 and allows you to monitor fuel data through your smartphone. This feature helps ensure that your ethanol mix is precisely calibrated, preventing engine damage caused by running incorrect fuel blends.

• Custom Tuning Required:
  To achieve optimal performance and fuel delivery, custom tuning is required. Calibration changes must be made before starting the vehicle to avoid damage and potential warranty voidance. Spool Performance provides tuning assistance by offering calibration details to your existing tuner or connecting you with experienced tuners.

Why You Need It:

If you are running high-output builds, larger turbos, or ethanol-based fuels, the stock high-pressure fuel pump (HPFP) on the M177 engine will struggle to meet the increased fuel demand. The Spool FX-170 provides the necessary fuel flow to ensure that your engine runs smoothly at high power levels, preventing fueling issues that could hinder performance. With E85 compatibility and 50% more flow, it is the ideal choice for enthusiasts looking to push the limits of their engine.
