This Genuine Briggs & Stratton OEM Fuel Pump is used on many Briggs & Stratton Intek single-cylinder engines and V-Twin engines that use a vacuum-operated fuel pump. The fuel pump moves fuel from the gas tank to the carburetor. Over time, the internal diaphragm can wear or become damaged, causing fuel delivery problems. A failing fuel pump can lead to hard starting, poor engine performance, or fuel leaking into the crankcase. Please verify your engine model number to ensure this part is correct for your engine.
