The fuel caps, also called fuel tank cap, and fuel tank cap and filler seal off the fuel tank and prevent fuel and impurities from evaporating.
The primary role of a fuel tank cap is to create a tight seal that prevents fuel vapor from escaping the fuel tank through the filler neck. By sealing the tank, the cap inhibits fuel evaporation, reducing harmful emissions and saving you money at the pump. Additionally, a properly functioning gas cap prevents contaminants such as dirt, dust, and water which can cause engine damage and affect performance from entering the fuel system. The fuel tank cap also aids in maintaining the safety of your vehicle by minimizing the risk of fuel leaks and fires.
