BMW 1 Series F20 / 3 Series F30 Fuel Pump Assembly 16117243974 Fuel Module Stable Fuel Supply

When BMW 1 Series F20 or 3 Series F30 require multiple ignitions to start in cold conditions, or experience weak acceleration, body vibration, or sudden stall during driving, this is typically due to aging fuel pump assembly causing insufficient fuel pressure. The part functions by stabilizing fuel pressure through the fuel module to ensure continuous and even fuel supply under all operating conditions, providing smooth power output. OEM number 16117243974, fits BMW 1 Series F20/F21 and 3 Series F30/F31. Installation requires relieving fuel system pressure first and replacing the fuel pump filter to prevent impurities from clogging the new pump.
