Spool FX-170 Upgraded High Pressure Pump Kit [M278]

The Spool FX-170 is a powerful upgrade to the high-pressure fuel system on the Mercedes M278 platform, designed to significantly boost fuel flow and support higher ethanol concentrations and larger turbochargers. With a larger bore size than the stock pump, the FX-170 delivers roughly 50% more fuel, making it an essential upgrade for those looking to maximize performance without sacrificing reliability.

Features and Benefits:

• 50% More Flow: The FX-170 boasts a larger bore than the stock pump, allowing for a 50% increase in fuel flow, which is critical for high-performance applications.

• E85 Compatibility: Fully compatible with ethanol fuels, the FX-170 is designed to work with higher ethanol blends, ensuring a consistent and reliable fuel supply for tuned engines running on E85.

• Plug-and-Play Installation: No cutting or splicing is required. The FX-170 is designed to be a straightforward, plug-and-play installation for ease and convenience.

• Support for Bigger Turbos: With increased fuel flow, the FX-170 ensures that engines equipped with larger turbochargers get the necessary fuel for optimal performance.

Why You Need It:

The stock high-pressure fuel pump on the M278 engine can limit tuning potential, especially when running larger turbos or ethanol blends. The FX-170 solves this by delivering 50% more fuel, raising the platform's fueling capacity and supporting higher horsepower builds with ease.

What’s Included:

• 2x FX-170 upgraded high-pressure fuel pumps
• 1x Ethanol Content Monitor kit with mobile app (optional)
• 1x Bosch spec 10-micron high-flow fuel filter
• Upgraded fuel lines and all necessary installation hardware

Spool 10-Micron Filter Unit:

The kit includes a 10-micron filter unit, providing top-tier filtration to protect the high-pressure fuel system without introducing noticeable pressure drop. It ensures debris-free operation, helping to safeguard the pumps and injectors.

Spool Ethanol Content Monitor:

The Spool ECA kit offers real-time monitoring of in-tank ethanol content and fuel temperature through a mobile app. It features BLE 4.0 low-energy technology, allowing you to use your regular Bluetooth functions while connected to the SPOOL ECA module. The fuel lines are E85-compatible, ensuring long-lasting performance in ethanol-rich environments.

Tune Changes Required:

Installing the FX-170 requires calibration changes to avoid damage and voiding the warranty. Spool Performance can assist in providing calibration details to your tuner or help connect you with experienced tuners for optimal setup. Custom tuning is essential to extract the maximum potential of the FX-170.

Low-Pressure Fuel Pump Upgrade:

To ensure the longevity and proper functioning of the FX-170, a low-pressure fuel pump upgrade is recommended. Adequate low-pressure fueling is crucial to avoid damage to the high-pressure pumps, which rely on fuel for lubrication. Failure to upgrade the low-pressure system could result in warranty-voiding damage.
