A fuel cap assembly is a component often seen on lawnmowers and other lawn and garden equipment. It is made of durable black plastic and is used to ensure that fuel doesn’t spill out of the fuel tank. Over time, fuel cap assemblies can begin to wear out and cause problems. Sometimes this results in a cap that doesn’t tighten all the way or there may be a fuel smell when using a lawnmower or snowblower. If fuel is leaking, the cap doesn’t fit right, or the cap seems damaged, it’s best to replace it with a new component. This is a simple process that involves removing the original fuel cap assembly and fitting the new assembly to the lawn machine. This fuel cap assembly is a genuine OEM component that comes directly from the manufacturer. It is an individual part that is compatible with MTD, Murray, Cub Cadet, Bolens, Yard-Man, and Yard Machines lawnmowers, snowblowers, chipper shredders, and tillers. No tools are required to replace this component.
