This Wiki article should explain it. http://en.wikipedia.org/wiki/Pitot-static_system

It is not just the bowl pressure acting on the main jet, the fuel flow is also determined by the pressure difference between the well and the rest of the metering, the idle jet and the main discharge nozzle orifice.

Examples of pitot tube, static tube, and pitot-static tube.
