Mercedes Fuel Pump Replacement Kit - Bosch 540209

Product Information

The fuel pump and sender assembly is an integrated unit located inside the fuel tank that delivers pressurized fuel to the engine while monitoring fuel level for the gauge cluster. The pump ensures consistent fuel flow for proper engine performance, while the sender uses a float mechanism to provide accurate fuel level readings. Built with durable materials and engineered for precise operation, the assembly is critical for reliable starting, efficient combustion, and accurate fuel monitoring.

• Hard starting or engine stalling – caused by insufficient fuel delivery.
• Inaccurate or erratic fuel gauge readings – due to a failing fuel level sender.
• Loss of power under load or hesitation during acceleration – indicates a weakening or failing pump.
