Just as a follow up: My Mallory 140 series fuel pump has an external bypass adjustment screw with locking nut. I was able to bring the fuel pressure down to 6 psi from 12 psi. I then used a Mallory 4207 regulator to further bring the psi down to 3 psi and less if needed. Dual 3/8" outlets with a pressure gauge outlet.
