If the carburetor is exposed as on the dual Paxton Cobra , there is no need for the fitting.

Hey Randy, I think one still has to supply a vacuum/pressure reference if using the blow-thru hat over the carburetor as the fuel bowls are vented under the hat and therefore still witness blower pressure (and don't try to use externally vented bowls!
); and my Studebaker R2 (yeah, and we had a 289 and a Paxton before Ford did!
) is plumbed as such.
............... , I noticed a boss in the casting where the fitting was.
I'm not sure if it's a "correct" fitment for the Ford installations, but the Carter fuel pump #M6270 for a Mopar has had in the past an upper body with a boss provided which has been used for this, as known and borrowed in the past by us R2 guys; by drilling and tapping the boss and changing or modifying the lever for the Stude.
If interested one can go to: "Bob Johnstone's Studebaker Resource website and look up: Studebaker/Avanti Fuel Pump Mod. by Jim McCuan, for pictures worth a thousand words!
