Here is an OEM replacement fuel cap that can be used with a range of gas-powered lawn and garden machines. The fuel cap is used to protect the fuel tank from debris and dirt. It will also help to reduce air from getting into the fuel tank. If there is air or dirt in the fuel, it can make starting the vehicle more difficult or even impossible. Dirt in the fuel can also cause severe damage to the engine. A replacement cap is a simple fix to prevent these issues. Although fuel caps can last for years, there is always the chance that one could have been lost, damaged, or could suffer from too much wear and tear. The replacement cap can simply be screwed in place to replace the old cap. This is an authentic OEM replacement fuel cap that is sold individually. The cap can be used on many types of machines including tillers, log splitters, chippers, and other small engines. The fuel cap is compatible with many brands including Cub Cadet, MTD, Yard Machines, Yard-Man, and Troy-Bilt.
