A tank float gasket is an essential component in a vehicle's fuel tank. This gasket ensures there are no leaks between the tank float and the tank itself. Often made from rubber or plastic, the gasket is designed to withstand fuels and temperature fluctuations. Durability and strength are crucial for safe, long-lasting performance. If worn or damaged, it must be replaced to ensure the integrity of the fuel system. Thus, the tank float gasket supports the proper functioning of fuel level measurement in vehicles.
