The fuel feed pipe from the tank ( the one with the fuel filter on the end ) goes to the brass elbow on the carb, the one nearest to the pump cover ( cover held with one philips screw ) the pipe from the carb, nearest to the metering cover held with four screws, goes to the suction side of the primer, shortest nipple, the pipe then goes from the pressure side of the primer, longest nipple, back to the tank, the primer pulls fuel from the carb into the primer and back into the tank, not the other way round
