CT.0005 Carburetor Primer Bulb Fuel Pump Primer Garden Tool Parts

Primer bulb is a part used in the engine fuel system. It contains a rubber ball that pumps fuel into the engine through compression. When the engine is not used for a long time, the fuel may flow back into the tank. At this time, the primer bulb can be used to push the fuel back into the engine, making it easier to start. Primer bulbs are widely used in small engines, lawn mowers, chain saws, outboard motors and other mechanical equipment.

primer bulb is a small rubber bulb located on the carburetor of small engines such as those found on lawn mowers, snowblowers, and other outdoor power equipment. It is used to prime the engine by drawing fuel from the carburetor and sending it directly into the combustion chamber, which helps start the engine quickly. Some other words that can be used to refer to it are primer bulb, carburetor bulb, fuel bulb, or primer pump.
