The SEA CHANCE 50-15521 Fuel Sending Unit is a reliable and accurate solution for measuring fuel level in marine applications. This essential component is designed to provide precise fuel level readings to the fuel gauge in your vessel's dashboard.
The unit is constructed from high-quality materials, including a brass body and stainless steel float arm, ensuring durability and resistance to corrosion in the marine environment. The float arm is equipped with a diaphragm seal that prevents fuel from coming into contact with the electrical components, maintaining a clean and efficient fuel system.
The SEA CHANCE 50-15521 Fuel Sending Unit features a 3/4" NPT threaded connection, allowing easy installation and integration with most fuel tanks and fuel gauges. The unit is also compatible with both gasoline and diesel fuel systems.
The fuel level measurement is achieved through a variable resistance technology. As the float arm moves up and down with the fuel level, it changes the resistance in the sending unit, which is then read by the fuel gauge to display the fuel level. This design ensures accurate and consistent fuel level readings.
The SEA CHANCE 50-15521 Fuel Sending Unit is also designed with easy maintenance in mind. The float arm can be easily adjusted, and the unit comes with a spare diaphragm seal for added convenience. Additionally, the unit is submersible in fuel, allowing for installation in the fuel tank without the need for external venting.
In summary, the SEA CHANCE 50-15521 Fuel Sending Unit is a robust and accurate solution for measuring fuel level in marine applications. Its durable construction, easy installation, and maintenance-friendly design make it a valuable addition to any fuel system on a boat.
