This conversion kit is designed for those seeking to enhance the fuel delivery system of their beloved Datsun, providing improved throttle response, smoother idling, and increased power output.

Additionally, the kit comes with a set of jets and needles to accommodate various engine sizes and conditions, allowing for easy tuning to achieve optimal performance.
