Ok so far ive got the following parts-

2 intank walbro 450/465s for e85
Holley 160 lb injectors
Holley -8 fuel rails
20' -10 fuel line

What fuel pressure regulator to go with?

Also not quite sure on the fuel line layout. -10 feed y'd to -8 at the rails and -8 return? Looking to support 1000rw on e85. Any insight is appreciated.

Not to sure that those fuel pumps will get you to 1000RWHP.

Yea, they will get him about 1100rwhp or so.

Do a 50psi base, that way you have enough pump up to 20lb of boost.

You could Y right before the rails and the feed the back of both, or go in the back of one, crossover, then out to the regulator. Either way will work.

I like the aeromotive regulators.

I have used the aeromotive 13101 with good success

You'll have the same setup as me (-10 line from fuel pump, Holley -8 rails). Don't feed one rail and have a crossover to the second. For that much power, split before the rails. I'll be using -10 from the pumps, Y-split to -8 before the rails, and -8 return. That should work well for you, too.
