Put in a different way, would the mechanical fuel pump mounted on the right front area of the engine have two metal nozzles and a female threaded port, or just a single metal nozzle and a female threaded port. Any knowledge on this point is certainly greatly appreciated....

IF there is a return line, it would be a steel 1/4" line that runs just along side the bigger fuel supply line. There would be two connections at the tank, also.
