Q

explain how fuel is supplied to the engines with all pumps operating

A

center tank pumps produce higher pressure than main tank pumps. thus both engines are pressure fed from the center tank until the center tank quanity decreases to near zero. thereafter each engine is normally pressured from its respective main wing tank. If pump pressure is low engine can get fuel from a suction feed line that bypasses the pumps.
