Mercedes Fuel Pump and Sender Assembly - Genuine Mercedes 1634704094

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.

About Genuine Mercedes

You may not realize this, but the parts that make up your Mercedes-Benz are not necessarily manufactured by Mercedes-Benz. No cause for concern, as Mercedes-Benz designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Mercedes-Benz for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine Mercedes-Benz parts box and find an OEM branded part inside, simply with the addition of a Mercedes-Benz logo.
