Upgrade your Harley’s reliability and fuel system performance with the S&S Replacement Fuel Rail. Precision-machined from 6061-T6 billet aluminum and finished in a sleek black anodized coating, this direct-fit replacement eliminates the cracking and leakage issues common with the factory plastic fuel rail.
Built for strength and smoother fueling, the S&S aluminum rail increases internal fuel capacity to dampen pressure pulses, providing steadier fuel delivery and improved throttle response under all riding conditions.
