Remember... Atmosphere (@ sea level) is around 14 PSIA, which is still a pressure

Well of course you have atmospheric pressure, but that's not going to keep the bowls equalized in the case of different FUEL pressures between the bowls which is where I thought the conversation was stemming from. If you've got 8 psi in one bowl and 5 in the other from some odd fuel log, flow path, or heat related issue, atmospheric pressure is not going to "equalize" the fuel pressure in the bowls.
