Default Help me build a fuel system!

Hey guys, I need help building a fuel system for my 07 Silverado.

I'm going to be turning it up to roughly 1,200 horsepower, but I know very little about about fuel system upgrades.

Right now the truck is barely supporting 984 to the wheels with my twin stock pumps and one KB BAP feeding to the primary.

So, I want to run a return style fuel system, and I know I need to regulate after the rails, but I need to know:

1. What fuel pump(s) to run

2. What fuel line to run

3. Modifications that need to be made to the tank and whatnot.

4. A guide on how to do this right.

I don't want to fight a rich idle problem from excess pressure so how would I get around this? Hopefully someone who has a built fuel system will be able to chime in here.

Thanks for all of your time and consideration!
-Robbie.

P.S. I'm doing this on race gas, with ID1000 injectors. (114lb/hr at 58psi rail pressure.)

I would switch the intake to a walbro 255 then feed a 1-2 gallon suger tank with one big external pump. Then have a return style fuel sytem returning to the surge tank.

So intank 255 feeding a suger tank, then after the sugre tank a big external pump.

May get a little more responses in the FI section. More guys with modded fuel system setups there. Just a thought.

What about running a huge external pump inline after the stock fuel pump, with new bigger line all the way to the front?

The big fuel pump will be kicked on by a KB BAP system so we can adjust voltage, and only when the truck goes into boost. There will be a regulator placed at the back of the passenger side fuel rail set at 58psi, and then run the return feed line back to the tank?

Also the KB BAP has a 30AMP fuse so that should be plenty enough to feed a big pump, and it will only be running when the truck is in boost for which I will retune the ECM to handle it.

What do you guys think of that?

Is this going to be a street driven vehicle? What fuel? I like the surge tank idea better than a huge in-tank system. Im not sure what the big aeromotive or magnafuel pumps are rated to but one of those in a 1-2 gallon surge tank with a regular pump feeding it.

Yup, drive it everyday! It'll be running on Race Gas, or as I know(111 octane) for the drag and Texas Mile sessions. No corn here.

I was thinking running that huge external pump inline with the primary and then running a separate pick up tube into the tank exclusively for that fuel pump to draw from, that way it won't starve the other pump.
