Correct on the no return line. All VaporWorx systems are intended to be single line to the fuel rail. If used in a return line arrangement fuel module performance will suffer.
Your plan for stainless hardlines and flexible PTFE ends is a great chioce. I've been running the same setup since 2002 with zero problems and have even reworked the lines with ease. Just be sure to properly support the line that goes to the fuel module outlet. You do not want to have excessive strain applied to that end. Since it is plastic it will easily break.
AN6 is sufficient for the power you're looking for.
