Why Upgrade to Stage 3 LPFP?

As power levels increase—whether through upgraded HPFP systems, larger turbos, or higher ethanol blends—the stock low-pressure fuel pump becomes a critical bottleneck. The Stage 3 LPFP upgrade from Spool Performance solves this issue, ensuring a consistent, high-flow fuel supply for even the most aggressive setups. This upgrade is ideal for:

• High-boost builds
• Flex-fuel conversions
• E85-powered engines
• Race-ready street cars
• Vehicles targeting 1200whp+

Tuning and Calibration:

Custom tuning is required when upgrading to the Stage 3 LPFP. It's crucial to work with an experienced tuner who can properly calibrate the fuel system and maximize the performance of your upgraded setup. Spool Performance can provide tuning details to your existing tuner or help connect you with professional tuners who are familiar with the Stage 3 LPFP system.

Low Pressure Fuel System Considerations:

To ensure the Stage 3 LPFP operates optimally and prolong the lifespan of the system, upgrading your low-pressure fuel system is essential. Proper low-pressure fueling ensures consistent lubrication of high-pressure pumps and injectors, preventing premature wear or damage. Failure to address low-pressure fueling can lead to system damage and void warranties.

Upgrade your Mercedes-AMG E63, CLS63, GLE63, S63, or SL63 with the Spool Performance Stage 3 Low Pressure Fuel Pump—the perfect solution for maximizing fuel delivery, reliability, and performance in high-power applications.
