Spool Performance FX-200 Upgraded High Pressure Fuel Pump System | SL63 AMG [M177]

Unlock the hidden performance potential of your Mercedes-AMG SL63 M177 with the Spool Performance FX-200 High Pressure Fuel Pump System. Engineered for enthusiasts who demand more from their platform, the FX-200 provides up to 80% more flow than the factory pump, supports ethanol blends, and is plug-and-play with no splicing or modification required.

What is the FX-200?

The FX-200 is a high-performance, E85-compatible high-pressure fuel pump upgrade featuring a larger bore design for increased fuel volume. This upgrade delivers approximately 80% more flow compared to the factory unit and supports fuel pressures up to 240 bar (24 MPa). Increased pressure boosts fuel injector output and reduces injection times—key factors when running larger turbos or ethanol-based fuels. It is fully plug-and-play, ensuring straightforward installation without any cutting or custom fabrication.

Why Do You Need It?

The factory HPFP on the M177 engine becomes a limiting factor when tuning or adding performance modifications. As power increases, so does the need for fuel delivery, especially when using ethanol or upgrading to bigger turbochargers. The FX-200 alleviates this bottleneck by delivering the flow capacity needed to safely and effectively support high-output setups.

• +80% More Flow Over Stock HPFP

• Supports Higher Ethanol Concentrations (E85 Ready)

• Capable of Pressures Up to 240 Bar

• Enables Big Turbo and High-Boost Applications

What’s Included in the Kit:

• 2x FX-200 High-Pressure Fuel Pumps

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

• Upgraded PTFE Braided Steel Fuel Lines

• All Necessary Installation Hardware

• Optional: Spool Ethanol Content Monitor (ECA) Kit with BLE 4.0 and Mobile App

Spool 10-Micron Fuel Filter

This premium fuel filter provides industry-leading filtration for the Mercedes platform without any noticeable pressure drop in the low-pressure system. It ensures the FX-200 and injectors remain protected from debris, safeguarding the integrity and longevity of your upgraded fuel system.

Spool Ethanol Content Monitor (ECA Kit)

Monitor in-tank ethanol content and fuel temperature in real-time via Bluetooth Low Energy (BLE 4.0). Seamlessly integrates with the SPOOL mobile app while maintaining connectivity with other Bluetooth devices. Designed for accuracy, durability, and 100% E85 compatibility, the ECA kit is ideal for users running ethanol blends.

Tune Calibration Required

The FX-200 HPFP upgrade requires tune calibration to function correctly and safely. Starting the vehicle without calibration can cause damage and void your warranty. Spool Performance provides the necessary calibration data to your existing tuner and can assist in connecting you with experienced tuners. While Spool does not offer tuning services, they are committed to supporting your tuning team.

Low Pressure Fuel Pump (LPFP) Compatibility

Proper LPFP support is critical for maintaining consistent fuel delivery and avoiding HPFP damage. The FX-200 relies on fuel flow for piston and bore lubrication. Inadequate LPFP performance can result in internal wear or failure, which is detectable and not covered under warranty. Ensure your fuel system is properly matched for high-performance builds.

Engineered for Power and Precision

Whether you're running higher boost, ethanol mixes, or a big turbo setup, the Spool FX-200 HPFP System is designed to keep your SL63 AMG (M177) reliably fueled and performing at its best. With unmatched flow, pressure capabilities, and installation simplicity, this upgrade is the foundation for your next power milestone.
