This fuel cap provides covering for the fuel tank and fuel line of the lawn tractor so that debris cannot enter through the fuel line and damage the engine.The fuel cap might have to be replaced at some point within the standard lifespan of the appliance if it cannot serve its function of protecting the engine from damage.
