Spool Stage 3 Low Pressure Fuel Pump | AMG C43/GLE43/E43 [M276]

Spool Performance is proud to present the production version of our Stage 3 Low-Pressure Fuel System, developed specifically for the Mercedes-AMG M276 platform. Designed to eliminate the low-pressure fuel pump bottleneck, this system is ideal for enthusiasts pushing for high horsepower, particularly when running E85 fuel.

As high-pressure pumps advance to fully support DI fueling, the demand on low-pressure electric fuel pumps has become a critical limitation for achieving peak performance. Our Stage 3 solution addresses this with a twin-pump configuration, where one pump operates continuously, and the second activates during boost onset for seamless power delivery.

This advanced fuel system ensures robust fueling, supporting over 1000whp, regardless of fuel type, making it the ultimate upgrade for high-performance builds. Whether you're chasing records or maximizing reliability, the Stage 3 Low-Pressure Fuel System has you covered.
