Mercedes Fuel Pump Assembly - Bosch 66161

Product Information

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 pressurizes 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.

• 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.
