Spool Performance Stage 3 Low Pressure Fuel Pump | AMG C43/GLE43/E43 [M276] - SP-LS3-M276

The Spool Performance Stage 3 Low Pressure Fuel Pump (LPFP) is engineered specifically for the Mercedes-AMG C43, E43, and GLE43 models powered by the M276 engine. As high-pressure pumps have evolved to fully support direct injection (DI) fueling, the stock low-pressure fuel pumps now present a critical bottleneck when pushing for high horsepower, particularly on E85 fuel. The Stage 3 LPFP upgrade eliminates this limitation, featuring a twin-pump design that delivers a seamless boost-onset fueling solution.

Designed to support over 1000whp regardless of fuel type, this advanced fuel system ensures your AMG C43, E43, or GLE43 receives the necessary fuel delivery for high-boost applications, big power builds, and E85-fueled setups. Whether you’re chasing track records or aiming for maximum engine reliability, the Stage 3 LPFP is the ultimate solution to ensure consistent, high-performance fueling.
