350lph fuel pump and stock pressure regulator?


Registered User
Will the stock fuel pressure regulator behave as normal if supplied by a 350lph pump, or will I see raised fuel pressure?
After the KB 2.1 install the 255lph pump struggle to keep pressure up at higher rpm's. So I'm contemplating upgrading the fuel pump to the Walbro GSS350G3 350lph, but will I also need to upgrade the regulator? -stock fuel rail and lines.
