Electric pumps pump their max flow rate the moment you turn them on. If you have a 250 HP capable fuel system and a 200 HP engine, when you are driving around town using 25 HP to move the car, you actually return 225 HP worth of fuel (250-25) to the tank. That means a prudent fuel system designer would provide a return capability nearly equal to the feed capability.

Aeroquip has an excellent page on fluid velocity (volume) through their hose and how to select the proper hose sizing to optimize this dynamic...

This would be a mistake of considerable proportions.
