With two deuces you might want to use a dual port fuel manifold with a pressure regulator. An engine driven pump might do OK if it will fit but will be kind of out of place with the more modern equipment there. An electric pump usually does well if it's as close to the tank outlet as you can get to reduce the draw side to minimum. That way you would have a positive pressure most of the way up to a two port fuel manifold with regulator on the firewall. Many a dual and triple deuce carburetor arrangement have been set up this way over the years. 97 heaven has a photo of a four barrel carb adapter to twin 97s on their site but I don't know if it's a bolt up to what you have or not. Chances are good that it is. Bolt up stuff makes life simpler for sure.
