If your BMW is stalling or won't start due to fuel pressure problems it could be due to a worn-out fuel pump. This replacement fuel pump assembly sourced from Bosch will perform just like the original one installed in your car from the factory.
Fuel Pump Module Assembly
A fuel pump module assembly is a complete unit, typically located inside the fuel tank, that delivers pressurized fuel to the engine. Unlike a standalone fuel pump, the module will sometimes include:
- Electric fuel pump – draws and pressurises fuel.
- Fuel filter/strainer – removes debris and contaminants.
- Fuel pressure regulator – maintains consistent fuel pressure.
- Fuel level sending unit – communicates fuel level to the gauge.
Key functions:
- Supplies pressurized fuel to the injectors for combustion.
- Maintains proper fuel pressure under different driving conditions.
- Provides accurate fuel level readings to the dashboard gauge.
Fuel Pump Module Assembly Failure Symptoms
- Engine stalling or no-start condition – pump fails to deliver fuel.
- Loss of power or hesitation – weak fuel pressure causes poor acceleration.
- Hard starting – requires long cranking before the engine runs.
