Fuel Line Choice and size

@Rat Bastid
Thank you for this response. I was considering going from the pump back to the tank for the return but your thorough explanation makes a lot of sense. Most likely the way i will be plumbing it!! Thanks!!
Wait explain your thoughts a little please. You SHOULD be running the return from the regulator all the way back to the tank. Your response sounds like you’re not going to do that.
