Mercedes Fuel Tank Sending Unit Left (C320) - Genuine Mercedes 2034700541

Product Information

A fuel tank sending unit is a component located inside the fuel tank that measures the amount of fuel remaining and sends this information to the fuel gauge on the dashboard. The sending unit consists of a float, a metal rod, and a variable resistor. As the fuel level changes, the float moves up or down, causing the resistance to vary, which changes the signal sent to the gauge, indicating the fuel level.

• Inaccurate Fuel Gauge Readings: A failing sending unit often causes the fuel gauge to show incorrect fuel levels, such as always reading full, empty, or fluctuating unpredictably
• Stuck Fuel Gauge: If the float or sensor mechanism gets stuck, the fuel gauge may remain in one position, regardless of the actual fuel level
• Fuel Gauge Reads Empty with Fuel in Tank: A sending unit failure may cause the gauge to read empty, even though there is fuel remaining, leading to unnecessary refueling or inconvenience
