I am converting from EFI to dual SU's in my 1975 280Z. I will use the fuel tank and the metal fuel lines that are in my '75. I was thinking of using the stock EFI fuel pump, which is at 36psi. I saw a 3 port fuel pressure regulator (Mallory 4309 High Performance Universal Fuel Pressure Regulator) and was wondering if I could use this with the EFI fuel pump.? Or is the EFI fuel pump too much for this type of fuel pressure regulator.? I know that the SU's only need ~4 psi of fuel pressure.
