I have a boosted 03' Accord V6 and am running RC550cc injectors. The way the stock fuel system is setup is a problem. The fuel first goes to the rear bank and fuel rail. then off of that its fed to the front bank and fuel rail. This system is non-return. The problem I'm having is the rear bank which gets the fuel first is starving the front bank. So would a FP regulator correct the problem or do I need to make a fuel return for the system to operate properly? If I read my 02 sensor which is placed after the turbo where both banks A/F ratio has combined my 02 reads good. But after checking the spark plugs and seeing how rich the rear bank is compared to the front bank I know there is a problem with the fuel delivery.

Thanks for any help in advance.
