The CNPAPC Fuel Tank Level Sending Unit Sensor is designed to accurately monitor the fuel level inside the tank and transmit stable resistance signals to the vehicle's fuel gauge. A faulty fuel level sending unit may cause incorrect or fluctuating gauge readings, making it difficult to determine remaining fuel. This replacement sensor helps restore normal fuel gauge operation and dependable fuel level indication. Manufactured to meet original equipment specifications, this unit replaces OE Part Number 25060-4S426 and is engineered to provide consistent signal output under normal driving conditions. The sensor responds smoothly to fuel level changes, helping maintain clear and readable fuel gauge information for the driver. Built with fuel-resistant materials, the sending unit is designed to withstand long-term exposure to gasoline environments. The durable float arm and stable internal structure support reliable operation and reduce the risk of signal interruption caused by wear or deformation over time. This fuel tank level sending unit is a direct-fit replacement for select Nissan Frontier 3.3L V6 models from 1999 to 2004 and Nissan Xterra 2.4L / 3.3L models from 2000 to 2004. It installs using factory mounting locations and does not require vehicle modification. Each package includes one fuel tank level sending unit, exactly as shown in the product images. Please compare the part number, connector, and overall appearance with your original unit before purchasing to ensure proper compatibility.
