Reasons to eliminate the stock fuel pump: Just another point of failure. Cleaner access to front exhaust connection. Cleaner routing of fuel lines to carbs. Excuse to craft a spiffy block-off plate. I recommend the 'solid state' pusher pump that you mount near the tank. They are available in 6 volt or 12 volt versions. They can be used either positive or negative ground. They are available with 2-3 psi output, perfect for B&B or Stromberg carbs, and no need for a regulator. These pumps are very popular with the Jaguar crowd. They cost around $40. Mount a good inline filter between the tank outlet and the pump.
