70F100 Gen3 twin 58 fuel system help needed

[AmericanMadeTrucking]

Hows it going guys, I have a little bit of an out of the box build. I've got a stock gen3 coyote a10 with twin 58s in a 70 f100. Im putting together the fuel system now. So far i have a dw810 brushless fuel pump and id1050x Injectors. Goals are 8-850rw on e85. And whatever we can safely make on 91 for when its just being cruised around town. Trying to get some input on fuel line size, what fuel rails are preferred, are 2 regulators necessary and routing. Any help is appreciated. I tried searching but being its not really a typical build.i figured id ask. Here's some pics of the build

Man, that’s a beautiful truck!

I was told by Aeromotive that -8 feed and -6 return lines are good for up to 1200 hp. I am going to be running a DW X3 fuel system with a single regulator in my Gen 3 car with -8 and -6 lines on E85 which will have a single 88/96 turbo.

Have youn checked out Deatschwerks’ Coyote fuel rail kit?

The DW X3 can run one 810 brushless or one DW440 and two DW 400 brushed pumps btw.

I should also mention that I’ll be running an Aeromotive/VaporWorx PWM triple pump controller which will allow me to run on one pump until there is a demand for more fuel, at which time the other pumps will turn on.

Awesome project!

800-850 rwhp with twin turbos on e85 will not require a ton of boost…or fuel so there’s no reason to over complicate it. A 3/8” line will be plenty for that, and even allow much more.

I see you already bought the pump and injectors, but both are overkill. The injectors don’t have any real downside, since you already have them, but the dw810 does. A single stock gen3 pump at 18 volts or potentially a dw400 at 15 volts (no bap) will support that power level and maintain pcm fuel pressure control. No return line needed either, so it cleans up the whole installation. Another option is the new dw550, which wouldn’t even require an increase in voltage on your application.

What’s going on with your gdi pump in the engine pic?

Thanks for the replies guys. The goal is to over build the fuel system on the first go so if I decide to bump up the power it'll be there. Im using an aftermarket fuel tank that doesn't have a standard mustang style pump hat. Im also using a frpp gen3 control pack which is setup to use a return style system and also doesn't allow use of a stock fpdm. So thats why I thought id go the dw810 since its got a dual speed controller. I will admit I ordered it without a ton of research but im hoping we can trigger the high speed cycle by tps.

I figure going with a set of aftermarket rails will clean up the plumbing side of things. Was just planning on doing -8 Feed/ return since the cost is negligible over -6 and will support whatever may come down the road. What i am unsure of is fuel line routing between the port an di systems. Coming from the LS world this di stuff is definitely a whole new game.

In the engine bay picture the hpfp is missing as my engine did not come with one.

That's unfortunate that you can't run a PWM fuel system. I always hate staged and triggered fuel pumps because they decide not to work when you need them the most and you don't know it until it's too late.

The DI pump will support up to 1/2 of your fueling at that fuel flow level. You just need to feed it with an adequate fuel line. I would recommend sourcing a stock GDI pump feed line because it has a check valve built into it. I actually have one lying around here somewhere...
