CRJ-700/900 Systems

They want a report on the fuel differences? Should have asked for a report on ecs diff's.
700/900 bigger tanks, 19,595 total pressure fueled vs. 14,518 for the 100/200
APU feed 700/900 a dedicated dc powered apu fuel pump from left collector tan. 100/200 APU and crossflow share the DC pump fuel taken equally from both wing tanks for the APU.
Crossflow 700/900 bi-directional pump to transfer from one wing to another. 100/200 dedicated xflow/apu pump and transfer valves used to transfer from one wing to another.
That’s it! Pretty damn similar.

Why don't you do your own homework before opening your mouth. Pretty sure I've already passed the checkride for the 200 series, so you can just stop right there. I don't need people to do my work for me. It was a simple question meant only for those who have a legitimate response.
