Hey guys, im running a 5.3 and s475. looking for about 800-900 hp. using an ls6 manifold with holley billet fuel rails, The fuel rails came with 4 -6 fittings. Id like to run dual feeds y'd from a single line from pump and dual returns to the pressure regulator, then single line out of the regulator to tank for return.

My question is what size should I use for the line from pump before I Y it to dual -6 into the rail?

Then what size from regulator to tank for return?

Also i would assume that a dual -6 feed would be more than enough for 800-900hp correct?

Thanks for any and all info!

Keep it simple, Run a -8 line to the Y block before the rails, and then a -8 return back to the tank.
