Fuel-It BMW N54 and N55 Stage 1 LPFP Low Pressure Fuel Pump Upgrade Kit for 1M, 135i and 335i
Unlock reliable fuel delivery for your tuned BMW with the Fuel-It Stage 1 LPFP inline upgrade kit. Designed specifically for BMW N54 and N55 engines in the 1M, 135i and 335i, this low pressure fuel pump upgrade works inline with your stock LPFP to deliver approximately 50 percent more flow when combined with the factory pump. It is fully assembled and ready to install, featuring the proven Walbro GSL392 pump and ethanol compatible hardware.
Ideal for fast-road and track-focused builds running pump fuel, this Stage 1 LPFP upgrade supports around 300 to 500 whp when paired with a healthy stock low pressure pump. Expect stronger low pressure fuel supply under load, improved consistency on tuned cars and peace of mind for spirited driving.
We have used this kit ourselves and fitted it for customers, and feedback has been consistently excellent for both performance and reliability.
