I have never found a fuel pressure specification in the Carter information in my possession.
Chevrolet specified fuel pumps with a pressure range of 3 psi to 3 3/4 psi for the Chevrolet sixes from 1932 to 1949 (Carter W-1's).
The allowable fuel pressure will also depend on the orifice in the fuel valve seat.
As far as Stromberg is concerned, many enthusiast infer than any reference to Stromberg carburetors mean the so-called Stromberg 97, which is actually ONE of the Ford variations of the Stromberg type EE-1. This SPECIFIC Stromberg is rated at 3 psi.
But many common Stromberg carbs are rated higher than 3 psi (and some MUCH lower). Examples: 1946 Cadillac 5 psi, 1921 Lincoln 3/4 psi.
For the OP: I would suggest a "vapor return line" rather than a regulator IF the pump overfuels the carburetor. Before speculating, I would try the pump to see what happens. If you are in love with a regulator, forget the "dial type inlines" available for $19.95 to $39.95 at your FLAPS. These "regulators" are extremely useful for someone with a rabbit problem in their garden, and a strong arm! If you go with a regulator, acquire one with an internal bypass, and a return line.
