Spool Performance Stage 3 Low Pressure Fuel Pump BMW N55 F2x/F3x 235/335/435

Spool Performance is proud to present the production version of our Stage 3 LPFP (Low-Pressure Fuel System) for the BMW FXX N55 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. This is a complete drop in replacement unit and does not require any assembly or core returns.

DISCLAIMER - Primary pump connector melting is a result of high ekp demands in the tune. It is not advised to overload the primary pump especially when having a two pump solution. This type of damage would not be covered under warranty as it is not a manufacturing defect.
