Spool Stage 3 Low Pressure Fuel Pump | E550/CLS550/S550 [M278]
Spool Performance is proud to present the production version of our Stage 3 LPFP (Low-Pressure Fuel System) for the Mercedes-AMG M278 platform. With the use of high-pressure pumps now being able to support DI fueling, we have found the low-pressure electric fuel pumps that deliver fuel from the tank to the high pressure pumps to be a bottleneck while chasing high horsepower, especially on E85 fuel. The upgraded stage 3 low-pressure pump kits are a solution for that and it features a twin pump solution with one pump coming in during boost onset. This provides almost double the flow from a stock pump and should be more than enough for over 1200whp worth of low-pressure fueling regardless of fuel type.
