Bulb-Purge "snap-in" 530047721

This primer bulb, also known as a purge bulb, is used to push more fuel from the fuel tank into the carburetor of your small engine equipment, to help the engine start easier. Over time and through extended use and exposure to gas and oil, the bulb of the primer will eventually lose its elasticity and crack or break. This bulb is made of plastic and can be replaced by accessing the ignition system. Disconnect the fuel lines and pop out the bulb with a set of pliers, and once you pop in the new bulb, you just reconnect the fuel lines. This bulb is compatible with a variety of makes and models of small engine equipment and is sold as an individual part.
