I am sure you've thought about it enough to choose something sensible, but I am surprised by this routing. Normally, it's:

pump(s)----------rail(s)---------FPR-----------tank

Assuming I have understood your description properly, you've got:

pump(s)-----------FPR---------rails(s)
(return line from FPR to tank not shown due to ASCII art limitations)

Why'd you do that, Jim?

Ah the wonders of ASCII art! Where's the Star Wars link when you need it?
I agree, that setup confuses me as well.

Because with two pumps and -10 feed line, the ~2.5 feet of line and rail after the fuel pressure regulator isn't going to see any kind of pressure drop, and it's easier, cleaner, and cheaper to set up that way. It's also the way that B&B had it configured, and I think the results speak for themselves.

Typically, you'd see something like this, but I'm not doing it that way.

The one thing i saw on this kit that most other kits i looks at didnt have, is it splitting the feed fuel lines to both rails instead of running them in series. When you Y them instead of series you eliminate osilation which is a problem in big HP car.
