Important Fitment Information

Briggs & Stratton E-Series, EX-Series, 08P and 09P engines may use different carburetors and primer bulb configurations depending on the complete engine Model, Type, Code and production configuration.

This primer bulb is intended only for select applications originally using Briggs & Stratton 594281 / BS-594281 with a compatible primer-type carburetor.

Engine series, horsepower designation, equipment brand or physical primer bulb appearance alone does not confirm compatibility. Similar-looking primer bulbs may have different dimensions or connection configurations and may not be interchangeable.

Please verify your original primer bulb part number and complete Briggs & Stratton engine Model, Type and Code before ordering. Compare the nipple / connection style and approximate 30 mm diameter with your original primer bulb where possible.
