About This Product
This S&S diaphragm spring is a vital internal component for the accelerator pump assembly on Super E and Super G carburetors. It provides the return pressure for the pump diaphragm, ensuring that the pump is primed and ready for the next throttle application. Made from high-tensile spring steel, this component is designed to withstand the constant cycling and chemical exposure found within a Harley-Davidson fuel system. S&S replacement parts are the preferred choice for maintaining the legendary performance and reliability of their Shorty carburetor line. This product is sold in packs of 10, making it a cost-effective solution for shops and home mechanics performing regular service.
Manufacturer part number: 11-2278.
