Fuel advice to support 1000rwhp So here's the deal, I would like to build this fuel system so that when I do turn up the boost on my turbo 408 build I won't have to change much. So hear me out and PLEASE any advice is welcome.
Parts I've already bought:
Aeromotive Eliminator fuel pump
Aeromotive 100 micron fuel filter
Aeromotive 10 micron fuel filter
Aeromotive fuel pressure regulator with boost reference
Aeromotive fuel rails
Plans:
1st: I bought an 89 caprice fuel tank because it's metal and I bought a sump to have it welded into the stock tank.
2nd: I plan on running a 12AN line from the tank to the first filter. The reason for the 12AN line is because the eliminator requires a 12AN feed. Both filters and the pump will be joined together (Granted there's enough room on the inside frame rail).
3rd: From the second filter I plan on running a 8AN feed line up to the back of the driver side fuel rail.
4th: Running a 8AN crossover joining the front of the two fuel rails.
5th: And stepping down to a 6AN line out the back of the passenger side rail to the regulator. Then running a 6AN return from the regulator back to the fuel tank.
Please feel free to add any tips or opinions. You won't hurt my feelings. Thanks guys.

Sounds fine.
Although in a previous incarnation, I used an Aero distribution block to feed the rails, so they were in parallel, as opposed to in series.
I linked the exits into a single -6 to the reg though.
I chose a distribution block simply as it fitted better. Y pieces or Tee's take up a lot of room.

It is certainly preferable to do it, but not essential.
Depends on bore size of the rail etc. Obviously it is better to have a larger "reservoir" of fuel for each injector at any given time.
Large bore rails will help this, as will parallel feeds. The parallel feeds will slow the flow of fuel over the injector too and each supply only feeds 4 injectors, as opposed to a single line having to pass over all 8.
As you're aiming for bigger numbers, and parallel is really easy to do...I dont see any reason for not doing it.

Your proposed combo should also include a pump controller if you choose to go that route.
I can build you a nice dual intank setup that will easily support 1000rwhp.
It will work nicely during extended street duty as well as at the track.
It will be quieter & likely much less costly overall.
Plus I offer complete line kits for 1 stop shopping.
Please call if I can be of assistance.

I am using a pre 1991 caprice tank because it is still a direct bolt in to my car and its 2 gallons more and its metal so I can have the sump welded in. What 98 tank are you referring to? I don't know of any 98 tank that is a direct swap into a 96 b-body.

On the return side I'd just do whatever is handiest.
Some would run a line from each rail to the FPR.
I just run a 90 off one rail, thru a swivel tee passing over the other rail and then to the FPR, all in -6
Was just easier to bring a single line over than 2 lines.

Sorry guys, maybe I should've clarified earlier that this fuel system is for my 91mm turbo 408 LQ9/Th400 swap in my 96 Caprice. Thanks for all the info though. Atleast now I know if I ever get an f-body I know what year tank can have a sump welded in. LOL

-12an Feed line is some BIG line, If it were me I would put a 12an/8an reducer on it. You would save a hell of alot of money because even just the fitting for -12an are expensive as hell. Also, you've bought the fuel pump so your about 1/3 of the way there. Your going to spend about 350-400 on fuel line, 60 on an inline filter and 100 on -an fittings.

ur plans seems to be sound but i agree reduce down to an 8an line and save some money. i also agree with feeding the lines in parallel as opposed to doing it in series all u need is an aeromotive distribution block
