The horizontal runs were done with a gentle downslope with roughly 2-2500gph.

5000 gph??? Holy crap, which pump are you using and how big is this tank?

What's the purpose of the ball valves near the tank? Are they wide open during operation? If not, open them up and control flow at the sumo only. That alone might help.
