Function

The primer bulb allows the operator to manually pump fuel from the tank to the engine before starting. By squeezing the bulb, fuel pressure builds in the line and fills the carburetor or fuel system.

Replacing a worn primer bulb helps:

• Improve engine starting performance

• Ensure proper fuel delivery from the tank

• Prevent fuel leaks or air entering the fuel line

• Maintain reliable fuel system operation

Important Compatibility Note

Primer bulbs must match the fuel line inside diameter to ensure proper fit and fuel flow. Always confirm your fuel line size (5/16″ or 3/8″) before ordering to ensure compatibility with your fuel system.
