Default Parallel Fuel Rail Mod Queston

I'm planning on doing the Parallel fuel rail mod to my 00RS in the near future. I've checked out the mod on Ravensblade and understand exactly what needs to be done, but I can't seem to figure out one little detail.. What is the 3rd metal line that runs under the manafold?

There are 3 metal lines that run from side to side under the manafold. Correct me if I'm wrong:
Middle Line: Return from FPR
Line to front of car: fuel feed from Drivers Side to Passenger Side.
Line to Rear of car: ??? What is it? It appears to be a vacum line?

And one last question just for clarity. With a stock setup, is it configured with a single line leading from the fuel filter to the starting point in the fuel rail system, then a single line that returns from the FPR and is fed back to the tank via a single return line?

Thanx for any help.

Ok, I have a possible answer to my own question. Is the 3rd line a vaccum line that leads all the way back to the fuel tank? Some means to draw any fuel vapor out of the tank or something?

Anyone?

Hey Shane,
You're right about the stock setup. I just want to tell you that I did this mod and had a bunch of problems. Fuel leaks and high pressure problems mostly. I really recomend the Vishnu fuel rail kit!!! Whole new billet rails, all the T fitting, hoses, and hose clamp you need. It's a very nice kit! It also comes with an adjustable FPR, which your going to need anyway. After messing with my "modified" fuel system for about 3 weeks, I finally stepped up and bought the Vishnu rails. At the very least buy the adapter that goes in place of the stock FPR, and buy an adustable one. You're going to have high pressures and you're going to be running rich if you don't. And when you go turbo you're going to want a high flow fuel pump and an adjustable FPR anyway. You can check out my setup at the track next weekend!!!

if you flare each other sections you cut your chance for a fuel leak will be cut in about half. just make sure you use high pressure fuel injection style hose.

I have been considering this mod also. I would use Steel Braided hose as an engine fire due to a leaky hose would be a waste of a nice car. Just my .02

Well, I drew up a really nice plan to create a parallel system that did not require the removal of the intake manafold, and did not require the cutting of a single line. It used a number of AN fittings, Earls hose and hose ends, and some T adapters. It would have worked just fine, but the Earls fittings are not cheap. After I priced out all the parts, it was not much cheaper than the Vishnu Jammy Fuel Rail system. So I'm just going to go that route.

I don't suppose you'd be willing to post those plans? I'd be interested to see them, even if they aren't really viable from a cost standpoint.

Thanks,
JulianH

Sure, if someone wants to use my design, they are welcome to it. I have 1/2 the plan drawn up on my computer already. I'll see what I can do about the rest this weekend.

Skidd,

How did you not cut anything? Just wondering how you got around moving the FPR so that it runs in parallel and not series? That was the only reason you needed to cut the fuel rails. Just wondering...

Actuall, I haven't done the mod. I've decided to get the Vishnu Jammy Fuel Rails instead. But as for relocating the FPR, that requires something like the Weapon-R adapter. see the Mods section on the Ravelsblade site. He used one there. I've cleaned up my drawings, and will try to scann and post them on Monday.

Well, here are the 2 diagrams I came up with to do the Parallel fuel rail mod without cutting any lines, or removing the manafold. The one thing that isn't in the diagram is what to do with the fuel rail at the stock FPR. The only way to get around cutting there is to get your hands on a Weapon-R Adapter like the one on theRavensblade web site. Look in the mods section. All the hoses and fittings are AN #6.

Hope this might help anyone who wants to give it a go. I've decided to go with the Vishnu Fuel Rails.
I just threw the pics on my geocities site.

Whats the cost on the Vishnu rails for a gc8? So the only other thing needed is injectors and orings? Is it stock o rings?
Thanks!

Oh yeah who sells these?

From what I've read, the vishnu rails will fit stock injectors, but you'll need different spacers,and perhaps different o-rings. Hopefully I'll get an answer straight from Shiv before I throw him some money.

Shiv's a busy man! You have to call him. You use the old O-rings off the stock injecters. The rail kit comes with all spacers and bolts......It's a complete kit! It's a great kit! And Shiv is the only one that I know of that sellss them.

I can't remember. Do a search in the factory forced induction forum under fuel rails. Shiv posted the info a couple of months ago.

Hello,

Shiv has been super swamped lately. I just joined him at Vishnu and now we can be sure to answer all emails. We're currently aiming at (and succeeding since Tuesday) responding to every inquiry emailed to us within one work day. With an email volume of approx 100 emails a day, it's tough to get all the questions answered right away. Send email to sales@vishnuperformance.com and I'll get back to you. Call, too, if you'd like.

At any rate, yes, the price of the rails for the WJ25 is $395 and that should be the price for the WRX kit, too. I'll have to check with Shiv in the morning about whether we're currently selling the rails without the FPR and what that price should be.

As for availability... We have a couple running around right now, and we're meeting in the morning to work on scheduling for the in-house machinist. He's got pulleys, rails for miatas and subarus, flanges, and lots of other things that he's cranking out like mad. Since we go over everything with a fine-tooth comb, we're not as fast as some of the bulk suppliers, but we should be able to get those rails out by next week for sure.
