Well with my plans of running an efi 408, I guess I am gonna have to do an aftermarket fuel system. I have seen the aeromotive kits on summit and their site for $1600-$1800. I want to kind of stay within reason. What have you guys done? Parts, price etc? I guess the biggest problem is that the braided lines wont match up to the lines that come out of the tank? Also what about wiring, do you use the factory wiring or aftermarket?
Let me see your aftermarket fuel systems

Depending on how wild this 408 is, and if it's Naturally aspirated, you very well may not need a fuel system at all.
Just a high pressure gss340 walbro pump, which is usually $125 bucks or less.
You can feed 500rwhp fed by a supercharger with one, so without the supercharger, you should be able to get upwards of 550rwhp NA.
I'm not sure how balls to the wall you are going on your engine, but in most cases people make less than 500rwhp without a power adder.
I've seen engines that make 477 at the wheels, at 7500rpm, run fine with a stock fuel system with a 190 pump and 30lb injectors.

I have the aeromotive system... tank, pump, lines, regultor and rails... better be safe than sorry
I figure you might as well do it right the first time so you dont end up spending doulbe in the long run once you want more power
did you buy this as the kit? How much does all that stuff run?
If your doing a full fuel system aeromotive is the way to go. You can piece things together, but its not gonna be chap if your doing a sumped tank, with lines fittings etc. etc.
I use a 255 lph in tank pump with a procharger external(same as t-rex pump i think), stock lines to an adjustable regulator, and 42 lb injectors which works well for me, and that should keep up with 500 hp. I'd post pics but there is really nothing to look at, the external pump is mounted near the tank in the rear and the tops of the injectors are green, but its a relatively simple setup that works.
it also depends on what intake you are planning on using, most of the aftermarket stuff is fine, but if you plan on using a TFS Box R, you need aftermarket rails, which means your doing at least a front half of the fuel system, which will cost $500 all day long

IS there a way to mount the stock lines to an aftermarket front half of the fuel system?
500rwhp is doable, but pushing the stock lines. Rails are fine, 255 LPH pump should be ok. 42lbs injectors or bigger...
Since you invited us to brag about our fuel systems, I won't fight it:
Behind Bars Race Cars Sumped tank
Aeromotive filter
Weldon 2025A (1400hp pump) w/ regulator
120 lbs injectors
Trick Flow regulator
Braided Steel lines in the engine bay
Regular fuel lines outside of it

Like i said before...Build your own Sump or buy the parts and have a radiator shop do it if you aren't confident about building a leak free sump. Along the chassis you use Aluminum Fuel line. With a Earls compression fitting that goes back to the braided stuff. If you use an Aeromotive a1000 Pump with the an-10 openings then you can do what i did and run AN-10 line from the sump to the engine compartment and then Aeromotive has a distribution block that has 2 AN-8 Outlets to go to each rail. Save money and use the original Fuel feed line as a return. If i kick my pump on my regulator reads about 40psi whether the car is on or off.
This is an EFI 408 right? If not then some of that return line stuff may not matter.

Can you give me a little more info on your setup, price, etc, rwhp? do you use the stock wiring to the tank? thanks
Yes it a efi 408. How much did all this cost? Was the rear sump the competition enginering one? How much rwhp are you pushing? do you use the stock wiring to the tank?
Hello... I have an 80 Capri that i'm trying to put a sump on. I'm kinda stuck right now with a couple of things..... My tank has the sending unit on the front of the bottom passenger side of the tank and not on the top as the pics of new tanks i've seen... Why is this?
Also, I bought a mustang sump from LRS which is supposed to conform to the stock tank. My problem is the end of the sump on the opposite side of the fittings is around a 1/2 inch from making contact with the bottom of my tank because of the recessed hump area on the tank. Has anyone else had this scenario??? I'm stuck on what to do at this point. 79-04 FUEL TANK SUMP, 1/2" FITTING OUTLET MUSTANG
This item here is what my tank has for sending unit... 81-84 FUEL LEVEL SENDING UNIT, 5.0L W/ CARBURETOR, REPRODUCTION, FITS 84 MANUFACTURED BEFORE 12/83 MUSTANG
and the new tank looks to take this one... 83-86 SENDING UNIT, FUEL TANK, W/ EFI, 5.0L MUSTANG
Does anyone have any advice???

I talked to extremely repudable sources today, and they said no you won't need a fuel system.
They suggested you don't even need the rails.
Goto napa and get high pressure 3/8 hose clamps and cut and clamp the stock rails to spread wider for the intake.
Use a gss340 intank pump, and some 36's or 42's with PMAS meter and you will be good to go.

Thank you for the info. I hope your source is correct. It would save me alot of money and time. I think I am gonna try your suggestion. Does the gss340 take the place of the stock pump, and does it use the stock wires too?
