I work on Honeywell TFE-731 engines and P&W 305A's. On the Pratts the jet pump is controlled by the motive flow valve located just outside of the aft fuselage tank in a Lear 60. On the 731's found on Lear 35, 45 and 55's the motive flow valve is located internally on the engine driven fuel pump.
My question is this: Do tranport cat. aircraft (A320, 737, 747 etc.) have these jet pumps located in the wings to supply the engines, and if so how are they controlled, with the fuel pump or a seperate valve.
