Fuel Sending Unit 51416191, 84254009 New Holland

The New Holland 51416191 Fuel Sending Unit (superseded by 84254009) is a genuine CNH OEM component designed to provide accurate fuel level monitoring in New Holland and Case IH tractors. Installed directly inside the fuel tank, this sender unit continuously measures the remaining diesel volume and transmits precise level information to the dashboard gauge, helping operators effectively manage fuel consumption and avoid unexpected interruptions during field operations. Engineered to original manufacturer specifications, the unit utilizes a float-arm and variable resistance mechanism that converts fuel level changes into electrical signals. As the fuel level rises or falls, the integrated float adjusts the resistance output, allowing the instrument cluster to display reliable real-time fuel readings. Manufactured from corrosion-resistant materials and fuel-compatible components, the sender unit is designed to withstand continuous exposure to diesel fuel, vibration, temperature fluctuations, and demanding agricultural working conditions. Its integrated sealing system helps prevent fuel leaks and vapor escape while ensuring long-term operational reliability. As a genuine New Holland replacement part, the 51416191 / 84254009 Fuel Sending Unit delivers dependable fuel level indication, precise fitment, and long service life. Replacing a worn or faulty sender helps restore accurate dashboard readings and supports efficient machine operation throughout the working day.
