This may sound like a dumb question but exactly how does the system work when putting the regulator on the return side anyway. I understand on a gas efi system but on a p-pump I can't really picture it. How do you stop from getting high pressure fuel (whatever an a1000 can put out) when the regulator is after the pump on the return side. Would you have to modify the stock return system, like basically remove all of the stock pressure regulating parts and just install a fitting with a new line? Like I said that may be a dumb question but I can't understand it.
