Float Fuel Sensor, Diesel, Probe Length: 20 mm

A fuel sensor, often a fuel level sensor (FLS), is a device installed in a vehicle's fuel tank to measure and monitor the amount of fuel present, relaying this data to a fuel gauge or telematics system. It typically uses a float and arm mechanism or a capacitive or Hall-effect sensor to detect changes in fuel levels and transmit signals to provide information on fuel availability, consumption, refilling, and to help detect fuel theft or pilferage
