Edlebrock Carburetor Fuel Pressure

I think that Walbro pump could be dropped sufficiently enough for a carb to function without issues.

I bought a Holley regulator years ago to drop the pressure from a mechanical fuel pump to low enough for a trio of SU Carbs which require a low pressure of 2 or 3PSI to function without flooding The SUs were sold but still have the regulator

Right now I am leaning towards the Agility fuel pump with it’s max pressure of 6PSI unless the Carter 74067 has a similar max pressure. The Carter also has the hydramax filter similar to the Holley in-tank system
