Fuel return question

[stilldreamin6772]

Putting together my fuel system. I know I need fuel injection line to the fuel rail but can I run regular fuel line for the return line. 2000 6.0 with regulator on intake.
Thanks

I ran mine all with -an...but the return to the tank from the regulator will be unrestricted flow,so regular fuel line should work,,but I personally wouldnt use it on mine....I would use the -an
