The ACDelco GM Original Equipment Locking Fuel Cap is a threaded cap that seals your vehicle's fuel tank filler, and is a GM-recommended replacement for your vehicle’s original component. The fuel cap has a rubber gasket that provides a liquid-tight seal to keep fuel in and water and dirt out. The cap may have a check-valve that lets air in or out depending on the air pressure inside the tank. This locking fuel cap has the added benefit of a lock to deter fuel theft. This original equipment locking fuel cap has been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.
