The 1948-1952 Shop Manual lists 4 psi Max pressure for the fuel pump and makes no distinction between years or engines.

Even though the specs say 4psi Max, the output of my pump at the carburetor is 2.5 psi and the truck runs just fine.

I'd rebuild the glass bowl pump and install it and see what happens.I'm sure it will work fine.
