Two carbs in that kind of application actually require less fuel flow to keep up because the jets are smaller. I know sounds weird. If the motor makes more power with two carbs., and what Mopar V8 doesn't, it has to use more fuel, correct  It takes X amount of fuel to make each HP, increase the HP output and the fuel consumption has to increase to make that power  True but you now have 4 float bowls each using less fuel than just two. If the systems flow was near or at capacity with two bowls it should be slightly less taxed with 4 bowls. Its not necessarily the pump either. Where you could get by feeding each carb on a tunnel ram with 5/16 line you may need 3/8 or 1/2 for a single carb. I know my 2 BG 750's use a lot.
