Actually, it's not called the "anything" driven pump.
It is called a high pressure fuel pump and is located in the FCU which is (75) bolted on the gear box of the APU or (73) bolted on a lube unit which is bolted on the gearbox of the APU and driven by the gear box.
Boeing have obviously decided that there is no need for a dc pump for starting as they have done away with it completly on the 73 NG.
I guess it has taken 30 odd years for them to come full circle and realise that the system that they employed on the 200 works just fine.
