This connector is designed to fit 5-90HP 2-stroke and TLDI outboard models from Nissan and Tohatsu. It mates with Sierra part 18-8089 to complete the fuel line connection, and it directly replaces OEM number 345-70250-0, making it a straightforward swap for owners who need to restore or repair a worn or damaged factory fuel connector.
