Has anybody tried this fuel system? I'm curious as to how much (boosted) horsepower it can support and what else is needed to complete the setup with some BBRC fuel rails. They're claiming 3/8" stainless steel supply lines, I'm assuming that's bigger than stock? The price is what really has me interested, if it can support 600-700 horsepower, I think it would be a great deal.

PRODUCT DESCRIPTION
Fuel Up Your High Horsepower Motor
This 1986-1993 Mustang SVE high performance fuel line kit w/ fuel pump is a great way to feed more gas into your motor. When making more power in your Fox Body, you are going to need a good fuel supply to keep your power constant. This kit includes a new Aeromotive fuel pump, new fuel pump hanger with 3/8" supply feed & factory bent 3/8" stainless steel supply lines. It also uses factory connection point for an easy installation. This is a great upgrade for Foxbody owners who have increased horsepower and need a better fuel supply. Pick up this kit at LatemodelRestoration.com and get your 5.0 running smoothly again.

Aeromotive 340 Stealth Fuel Pump
These Aeromotive 340 Stealth electric fuel pumps feature a compact, lightweight design that will bolt into most existing hanger assemblies. The 340 Stealth electric fuel pumps boast an impressive 340 lph flow at 40 psi. They are ideal for applications requiring more flow, while retaining the factory wiring and mounting provisions available in the OEM configuration. The Aeromotive 340 Stealth electric fuel pumps use a turbine pump mechanism that increases durability and can be used in pulse modulated applications. These pumps use a 3-inlet configuration that covers a wide range of vehicles. They also run reverse polarity, so they require the use of the included wiring harness for proper installation. The fuel pumps also include a 5/16 in. section of rubber hose and hose clamps.

The stock lines are 5/16th and can handle up to 500hp. That 340lph pump sounds good but remember that our fuel systems return unused fuel to the tank. There have been some threads about bigger pumps actually transferring heat to the fuel tank. With aftermarket fuel rails it shouldn't have a problem surpassing the 500hp limit of the stock stuff. Won't have to worry as much about pressure drops when full throttle. Sounds good to me [emoji106]
 
So if I add a Vortech V3-Si to my current combo will an in-tank 255lph with stock lines and rails support it? I'm hoping to make around 450 at the wheels. Car currently makes around 300rwhp. Last thing I want to do is run the thing lean while the block is already being tested.
 
Good to know. How do you connect the stock lines to the stuff in front of the sway bar?

First i drilled out the two existing holes to fit a -8an and -6an bulkhead fitting, unibit works best here.

Then I used a russell AN adapter to connect to the stock fitting, then a female AN union fitting, then a bulkhead fitting thru the swaybar mount, from there the -8an line goes to a Y block, splits the feed and that runs to each fuel rail, the return goes straight to the regulator.

I always thought that once you go past the 450rwhp mark, the entire fuel system should be upgraded.

I think you will be ok, but a blower setup may command more fuel, so that number could be lower. I estimate 700-715 fwhp, it has made 582rwhp on pump fuel, but i have a naturally aspirated combination. If you have the cash to spare, do the fuel system, i need to do mine but i have kept putting it off until now. I am doing it over this season.

Yeah, my plans are to add a Vortech V3 Si "tuner kit" from Anderson, come up with my own fuel system, and keep it conservative....450-470rwhp max. Still running stock bottom end parts. Another question I have is, if I run the SVE kit above and some BBRC fuel rails, how to plumb in a fuel pressure regulator with a boost reference.

I guess if nothing else I'll just have to spend a little more $ and get a complete system from Glenns.

Or, buy the standard Vortech kit with the T-Rex boost a pump and see if that does the trick.
 
@Jason 302 The boost reference regulator should be no different to hook up than a regular one, it takes manifold vacuum signal, and when that turns into positive pressure it adds fuel pressure.

Really your call on the fuel system, mine was originally built for a similar setup, 480rwhp HCI novi2000 combo. 255 in tank pump, external pump, to stock lines/rails with 42# injectors.

Creative. I dig it.

Im using that fuel line with a hfp 320 lph pump, sn95 rails, 80 lber injectors. My set up is tmoss ported cobra, gt40 heads, tfs1 cam, V3 si at 15psi. No idea how much power its making, but my fuel system is working well afr holds a 11.5 in boost. Install was a kind of a pain due subframe connectors, fit was good as well.

You will need more fuel pump than the 255lph. So the kit you linked is a good idea for your plans. The 340 will be more than enough pump(actually I believe around 700rwhp in a boosted application).

Hoping my 255lph and 60# injectors are enough for my V3 and top end.. I'm 300 rwhp and will probably be around 425-450 rwhp after the V3. We'll see when I get it dyno tuned.

Just a heads up Mike. I was talking to Nick awhile back about adding a V3. He said I definitely needed to upgrade beyond my Walboro 255. He said it wouldn't keep up. But good luck. Hope it works for you.

So do you guys think if I put a 340 in the tank along with some aftermarket fuel rails, it would be sufficient for my power goals?
Do aftermarket fuel rails have a spot for a regulator or is that something that will need to be plumbed in elsewhere?
Since the fuel rail is good to 500hp, do I even need an aftermarket set?
Do aftermarket regulators, like the Kirban that's currently on the car, increase pressure from boost or is that just the "stand alone" regulators that are usually plumbed in.

Stock rails are usually not a problem for your intended power level. Usually good to around 500whp FYI and that's usually around the blocks limit. So if it were me....id just keep stock rails,lines,and add the pump, inj,press regulator and should be fine.
