Spool Performance AMG GT/GTS/GTC/GTR [M178] Spool FX-170 Upgraded High Pressure Pump Kit

Unlock the full potential of your vehicle with the Spool Performance FX-170 High-Pressure Fuel Pump Upgrade. Designed to significantly enhance your fuel system, the FX-170 offers approximately 50% more flow than the stock pump, making it an ideal choice for those looking to increase ethanol concentrations or upgrade to larger turbos. This high-performance pump is fully E85 compatible and features a straightforward plug-and-play installation with no cutting or splicing required.

Why Upgrade to the FX-170?

The stock high-pressure fuel pump (HPFP) on M178 motors often struggles to meet the demands of high-tuned setups. The FX-170 addresses this limitation by providing a substantial increase in flow capacity, thereby supporting more aggressive tuning, bigger turbochargers, and higher ethanol blends. By upgrading to the FX-170, you ensure that your fuel system can keep up with your performance goals.

What’s Included in the Kit?

• 2 x FX-170 High-Pressure Fuel Pumps: Upgraded pumps that deliver 50% more flow compared to stock.
• 1 x Ethanol Content Monitor Kit (if selected): Includes mobile and watch apps for real-time ethanol content and fuel temperature monitoring.
• 1 x Bosch Spec 10-Micron High Flow Fuel Filter: Superior filtration without noticeable pressure drop.
• Upgraded Fuel Lines: Black nylon coated braided steel with PTFE core, 100% E85 compatible.
• All Necessary Installation Hardware: For a complete and easy installation.

Spool 10-Micron Filter Unit

Our 10-micron filter unit provides exceptional filtration for the M178 platform, protecting your high-pressure pump and injectors from debris without causing pressure drop in the low-side fuel system. This filter is highly recommended for maintaining the performance and longevity of your fuel system.

Spool Ethanol Content Monitor

The Spool Ethanol Content Analyzer (ECA) features a digital display of in-tank ethanol content and fuel temperature. With BLE 4.0 technology, it connects to your mobile device via Bluetooth, and the ECA module offers a 0-5V filtered output for flex-fuel setups if required. This comprehensive monitor ensures accurate and convenient ethanol content readings.

Tune Changes Required

The FX-170 pumps necessitate calibration changes to optimize performance and avoid potential damage. It is crucial to update your vehicle's tune before starting the car with the new pumps installed. Spool Performance can provide calibration details to your tuner or assist in connecting you with experienced professionals. Custom tuning is essential to fully exploit the capabilities of the FX-170 setup.

Low Pressure Fuel Pump Upgrade

Proper low-pressure fueling is crucial for the reliable operation of high-pressure pumps and injectors in direct injection systems. Inadequate low-pressure fueling can damage the pump piston and bore, potentially voiding warranties. Ensure that your fuel system build includes the appropriate low-pressure upgrades to avoid issues.
