Spool Performance E63 AMG [M177] Spool FX-200 Upgraded High Pressure Pump Kit

The Spool Performance FX-200 High-Pressure Fuel Pump Kit is designed to significantly enhance the fueling capacity of the M133 engine platform. Featuring a larger bore size than the stock pump, the FX-200 delivers roughly 80% more fuel flow, making it ideal for high-performance applications. This pump is fully E85 compatible and designed as a plug-and-play solution—no cutting or splicing is required. The increased flow capability allows for higher ethanol concentrations and supports larger turbo setups, making it an essential upgrade for enthusiasts seeking to push their M133 engine to new limits.

Why Choose the FX-200?

The factory high-pressure fuel pump (HPFP) on M133 engines limits the motor's tuning potential. By offering an 80% flow increase, the FX-200 HPFP removes these limitations, allowing for larger turbos and higher ethanol content blends, enabling greater performance gains.

Kit Includes:

• FX-200 upgraded high-pressure fuel pump
• Ethanol Content Monitor kit (optional) with mobile app
• Bosch spec 10-micron high-flow fuel filter
• Upgraded fuel lines and installation hardware

Spool 10-Micron Fuel Filter:

The included 10-micron fuel filter is designed to provide optimal filtration without causing a noticeable pressure drop. This filter protects the high-pressure pump and injectors from debris, ensuring long-lasting performance.

Spool Ethanol Content Monitor:

The Ethanol Content Monitor kit provides a real-time readout of the ethanol content and fuel temperature through the Spool mobile app. Powered by Bluetooth 4.0 technology, this system allows you to monitor your fuel system without interfering with other Bluetooth functions on your device. The kit includes 100% E85-compatible braided steel nylon core fuel lines for durability and reliability.

Tune Changes Required:

The FX-200 pump requires tuning adjustments to optimize performance and avoid any damage. Spool Performance can assist with calibration details for your tuner or help connect you with experienced tuners familiar with these pumps. Proper tuning ensures maximum performance and longevity of your upgraded fuel system.

Low-Pressure Fuel Pump Upgrade:

For optimal performance and durability, ensure your fuel system includes an upgraded low-pressure fuel pump. Insufficient low-pressure fueling can cause damage to the high-pressure pump and void your warranty. Spool Performance recommends planning your fuel system build carefully, especially when adding high-performance components.
