dual fuel regulators

May be more work than you want to go to, but what I did on a Pro-Mod car years ago was to build a small accumulator that the pump fed directly from one end. On the other end was a by-pass type regulator set to, eh maybe 12 psi, something above whatever the other regulators would be set to. Then along the body of the accumulator were bungs for a regulator for each bowl and each N2 solenoid. I'm calling it an accumulator, but that's not really what it is. Header Tank maybe? Anyway, it was a piece of 2" thin wall aluminum tube.
