Fore Innovations Fuel System: School Me How to Install (Pics Inside)

GM2Ford · Apr 23, 2017

I've got the L4 system.

I've got it mocked up to the lower intake manifold. Is this something I will figure out on the vehicle (length)? I'm not familiar with a return style set up, so I'm not sure which ports get the -10 feed and the -8 return.

Not really sure where this guy goes?

I removed 2 pictures that were ignorant and edited a new one to color coordinate the lines for better illustration and feedback.

Your mockup to the rails is good. It will go like this with how you have it laid out-

- single feed line to the Y-block (your picture)
- split lines from y-block to each rail
- from each rail to fpr
- single return from fpr to tank

Yes you will need to figure out how you want to run the lines on the car, where you want to mount the y-block and fpr before you determine line length.

I'd research deadhead setup if not familiar with it. Would be fpr before fuel rails.

This is the way I'd go. I ran a single feed line to the FPR which is in the pass side fender by the intercooler pump. A single line goes from the FPR to the Y and a line runs each side of the Y to the rear of the Fuel Rails. I then ran a front crossover to connect the two rails together, this helped provide a steady fuel pressure at the FRPS.

You have no idea how much this helped! I've got a better understanding of how it would go now! Thanks Bud!

What's FPR? Excuse my ignorance. Why is it called Deadhead?
I'll search it in the mean time.

This is the Deadhead setup I'm assuming?

FPR? Fuel Pressure Regulator
FRPS? Fuel Regulator Pressure Sensor?

After researching the deadhead setup, correct me if I'm wrong, but my understanding is...

Deadhead routing provides,
1. "Supposedly" steadier fuel pressure readings at the FRPS.
2. Doesn't recirculate "hot" fuel, due to it meeting a dead end at the fuel rail and forcing the "hotter" fuel (heated by the engine bay/hot rails) to be consumed during the combustion process.
3. Less hose/cleaner routing?

FPR- Fuel Pressure Regulator
FRPS- Fuel Rail Pressure Sensor

I would say that Dead head probably provides a less steady fuel pressure but its not really that big of fluctuation at least after I put my front cross over line on. If your tune is setup right the ECM will adjust injector pulsewidth based off fuel pressure.

The main improvement is the reduction in fuel temps.

I have like maybe a 75% understanding of how to route the lines the deadhead setup. I have no clue where the return line on the hat connects to then?

Also,

Is this the FPR? Because I'm not sure how the lines would be routed going the deadhead setup way?

Bdubbs · Apr 24, 2017

On the fpr, the bottom port is the return line. The other two are feed line. One of those will be the line coming from the pumps, the other is the line going to the rails.

NateDogg · Apr 24, 2017

Yes that's your regulator.. of those 90s will be feed and the line that goes to the rails.

The bottom port will be your return.

Do you have the Fore controller as well? How are you wiring it up? That's the part I'm confused on.

94slowbra1 · Apr 24, 2017

single feed line from your hat to a side port on the fuel pressure regulator (fpr). from the opposite side of the frp a single feed line to your y-block. 2 lines from the y-block to your rails. a crossover on your rails to help keep pressure steady on both sides. from the bottom port of the regulator a single return line back to the return port on the hat.
mount your fuel filter somewhere in the main feed line and make sure it is accessible so you can change it/clean it
if i remember correctly the hat is labeled feed and return and so is the regulator
the biggest advantage of the dead head set up is not having hot fuel recirculating and causing the pumps to shut down from overheating
wiring is another story.

OP this is a good thread for reference

I have the FC3 Controller, I haven't started the wiring yet. Right now I'm making sure I understand exactly how to route the feed/return lines and which ports they go to, etc.

+1 Thanks for really dumbing that down for me! This helped me a million!

Thanks! I'll try the deadhead route!

So I think I have everything pretty much figured out in theory. Next I need recommended locations for certain items.

Best places to mount the following:
1. FPR?
2. Y Block?
3. Fuel Filter?

Also, if anyone has pictures of their setup and where things are mounted, that would be extremely helpful.

I replied to your post on my wall. Just send me a pm.

Who did you buy the system from? They should have answered all this for you and made sure you were setup with the proper system for your needs.

94slowbra1 · Apr 25, 2017

Listen to ^^^^. Knows his stuff

Nightmare302 · Apr 25, 2017

I personally dislike deadhead setups. They "can" have issues with fuel pressure spikes and if for any reason your FPR were to fail you have nothing to take fuel to the rails. I always ran a -10 to y block in the passenger fender then -8 to each rail then -8 back to the FPR but that's me.

My understanding is if the regulator fails it's a diagram on inside. And if this happens it won't stop fuel getting to the motor. If anything you'll get more because it's not "regulated".

Someone correct me if I'm wrong.
