True, however this system is treating the LPG as a liquid fuel in the
same sense as conventional petrol/gasoline.

I was wondering if a standard LPG regulator would provide a constant
pressure output, in the same manner as the fuel pressure regulator in a
conventional gasoline EFI system. This would greatly simplify the
installation, no pumps required.
