Lets Build a DREAM FUEL SYSTEM
The 454 LS1 IMPALA SS project is almost done we are pulling the old motor today and installing the 454 LS1. PaiN from this site sold us his LS6 intake and custom fuel rails. We also used 30 SVO injectors. Now we need to build a fuel system from a fuel cell back i have this much figured out as this same setup is being built on my LT1. Im just not sure how much different the fuel systems are on LS1's
Here is the layout i have planned
-16 Gallon Fuel Cell w/ GM style sender
-100 micron filter
-Aeromotive 1000hp fuel pump
-10 micron filter
-10an feed line to rails not sure how if to feed both rails or just one?
-EFI regulator
-8an return line
Does anyone have a link to this kind of fuel system or pics.
Thanks
Mike

Re: Lets Build a DREAM FUEL SYSTEM (Mike TexaSS)
How much HP are you shooting for here?
My comments:
I had a 750hp car. I also had that 1000hp fuel pump and a fuel cell. I ditched it in favor of two intank walbro pumps. So much quieter and nicer and no fuel starvation problems. I could once again hear myself think in the car. Also 8an feed and 6an return is big enough (for 750 hp). You also have to think of the wieght of the fuel in that 10an feed line, it's getting to be a heavy column.

We are shooting for 530 RWHP through an auto. This is in a Impala SS so the stock tank is not a option. These cars were not designed to go 10's :lol:

Re: Lets Build a DREAM FUEL SYSTEM (Mike TexaSS)
Why is the stock tank not an option? You're allowed to run 10s with a stock tank, are you not?
My car made 630rwhp easily with what I mentioned at a max of 75psi fuel pressure, with no fuel pressure drop or creep. Just my experience...

The fuel pickup on a impala tank is in the front. You cannot launch a high impala SS without at least 18 gallons of gas! Or it will starve on the top end of the 1/4 mile...
Trust me been there done that.

Off topic - Curious as to why you are not modding the Vette instead of the Impala? Lighter car, better aerodynamics, etc... :smash:
Anyway, good luck with your project. :cheers:

Why not mount the intank pumps on brackets to locate them in the back of the tank then?
I don't know if you have any intention of driving this thing on the street, but with that fuel pump it's going to be majorly annoying. BTW, my fuel cell, with foam, (while it lasted) would starve on steep turns when it was 2/3 empty. I was sooo much happier switching to intank pumps. Cool setup, too, dual -6's with a NOS y-connector to one -8 then to a single -8, 10u filter. Second pump would only turn on if rpm was above 4k or boost was above 6 psi.
