Spool Performance Stage 3 Low Pressure Fuel Pump | AMG GT/GTS/GTC/GTR [M178] - SP-LS3-M178

Unleash the full performance capabilities of your Mercedes-AMG with the Spool Performance Stage 3 Low-Pressure Fuel Pump (LPFP), meticulously engineered for vehicles equipped with the M178 4.0L Biturbo V8 engine. Designed to resolve the fueling limitations of the factory low-pressure system, this high-flow, dual-pump upgrade is the ultimate solution for high-powered builds and ethanol-based fuel applications.

In modern high-output engines, the stock low-pressure fuel pump often becomes a bottleneck—especially when running E85 or pushing for four-digit horsepower. The Spool Performance Stage 3 LPFP combats this issue with an intelligent twin-pump configuration. One pump operates continuously for stable fueling, while the secondary pump is activated automatically under boost, delivering nearly double the flow of the OEM unit for uninterrupted fuel supply at wide-open throttle.

Capable of supporting over 1200whp regardless of fuel type, the Stage 3 LPFP offers the reliability and performance needed for both aggressive street driving and full-track builds. OEM-style integration ensures a seamless installation process, while the robust design maintains consistent pressure and volume under the most demanding conditions.
