This 150 micron Briggs & Stratton In-Line Fuel Filter is designed to maintain fuel systems health by straining out foreign particles before they reach the carburetor. Dirty or blocked filters can lead to diminished performance and uneven operation. The Briggs & Stratton fuel filter can be used for 7 to 15HP engines without a fuel pump and ensures proper fit and performance to maintain the life of your Briggs and Stratton engine.
