Product Description

This primer bulb is used to draw extra fuel into the carburetor, allowing the engine to easily start. The primer bulb fits various power tools and is sold individually. When the purge bulb is pressed it will force fuel into the fuel line from the fuel tank, ultimately leading it into the carburetor. When the carburetor is full with fuel, the excess will go back into the tank, specifically in the fuel return line. With use and wear, the primer cracks or loses elasticity, then it is important to replace this part. Refer to the manual provided by the manufacturer.
