3/8" fittings on the fuel pump will cause some restrictions. I would be concerned about that. You're running two pumps - does that mean you have two pick ups? If so, run -6 from each pick up to the pump. Then -6 out of the pump to a manifold that's -6x2 in, and -8 x 1 out. That should maintain full flow.
If there's only one pick up, I can't see a reason to run two pumps in series. Replace those two with a single high flow pump with -10 fittings. Like Aeromotive A1000 with the proper pressure regulater.
To make life easy, use braided hose from stem to stern. A little more expensive, but it sure is easy to run. You can have the whole thing done in a day.

I agree, 100%
