nice. so really all i need is a left hand side rail?

i can get all the other stuff cheap as but the main thing is just the rail itself?

roughly how long did this take you?

remember to put hose clips on all the tee joints lol

[nt_a_foz]

is there any difference when doing with a v5??

Got to do joshes car when we put motor in and got aftermarket split rails to go in but then do we need 2 regs??

[wrx_lou]

na just one aftermarket.

[nt_a_foz]

does it have to be aftermarket to run the rails?? similar to the ones i sold you bro

[wrx_lou]

Na i believe you can mod the factory one. But it might get a little expensive depending on how you go about it ie. weilding fittings on. maybe hit boostcut up about that. Dont you have a A/F reg anyway though?

[Guest boostcut]

bro... check out my fuel set up next time, i modifyed the standard fuel pressure reg and used the factory left and right rails, works a treat...

[nt_a_foz]

nah nah its not for me mines been done..

its for joshes..hes got those custom rials that were on my flipped manifold adam....they got the fittings and everyting on them already..

just trying to sus out the reg side of stuff

[subaru-mania]

Hey dudes im thinking of doing this to what one seems to work better?? and whats the advantages? also what about all that metal piping under manifold that has hoses off it and witch plugs into rails does that go?? thanks.

[Guest boostcut]

i can make you some if you want, i put a for sale thing up a while ago. i do this sort of thing for a living too if your worried about dodgy-ness

[subaru-mania]

im down mate i can get u the bits u need if u want to keep it on the cheep haha. what will u need?

[Guest boostcut]

4 3/8th elbows and two 3/8th tees. i have all of these in my truck at the mo. where are you from?

[subaru-mania]

[Guest boostcut]

Can you put pictures or explain how to do this please?!? ;D

I have seen this http://www.trademe.co.nz/Trade-Me-Motors/Car-parts-accessories/Subaru/Engines/auction-236666695.htm but where do the fuel regs go/what do I need?

[Guest boostcut]

yea the fuel pressure reg goes inline with the "return"from your rails. you can use your fpr i just cut the end off a rail and made a fitting up to suit, if you want i can make one and send to you for $40 give me a call/txt if your keen and il do it today 0272935871

Im part way thru this (and a few other mods) and im wondering what happens to the breather line or what ever it is 3rd fuel line near fuel filter- not fuel in or return, also there is 2 vac lines in relation to the fuel setup one is vac for the Fuel pressure reg and the other is on the throttle body, what happens to this line, can i just block it up?

CHeers

[chrisjunkie]

the third line is purge canister which goes to the green solenoid. Its safe to leave off. The vac lines NEED to be connected otherwise you wont get any fuel. Make sure that you get a t piece and tee the two fuel regs together at exact lengths. (read: the lines from each reg need to be the sam distance ) This same distance applies for your fuel line too. Make sure the lines are the same distance to the tee on both sides. This mod is parallel so hence why the equal distance rule applies. Hope this makes sense hard to write from a phone! Cheers chris

also, check the link in my signature and go into the modifications folder and there is pictures relating to the split fuel mod

[dubbedup]

Cheers, explaining stuff over the internet dam tricky sometimes....anyways....

on the throttle body there is a vac line that goes to steel lines and then to the carbon canister, which is removed and the vac lines are just joint up making a circuit for want of a better word - can i just block this line at the throttle body?

I cannot see any green solinoid....altho we might be talking two different cars....

The other bit i have issues with is what do do with the other fuel line it comes in from the bdoy near the fuel filter, three line one is in one is retun...what is the other one?.... can i just tuck it away or does it jsut need to be blocked etc,

Yeah it is. Where about are you located? Maybe I can help you do it?

Yeah you can. Doesnt really do much but get in the way and stop emissions when the car is warming up or something like that

I cannot see any green solinoid....altho we might be talking two different cars....

Lol quite possibly although they are mostly the same

Yep tuck it away or just leave that line dangling. As said its not very important

Here is my diagram on my site that should be fairly helpful url=http://car.chriswiggins.co.nz/Parts_and_Modifications/split_fuel_rail2.jpg]http://car.chriswiggins.co.nz/Parts_and_Modifications/split_fuel_rail2.jpg[/url]

Blue is fuel in, Red is fuel out and green is the vac lines onto both the fuel regulators. When I did this I thought fuel in started at the regulators but it doesnt. Fuel out is from the regs.

Make sense?

[dubbedup]

Yeah i understand the setup, it was just what to do with these two lines that had me stumped. Cheers

[chrisjunkie]

Cool glad I could help. The green solenoid either underneath BOV or next to throttle cable mount on manifold needs to stay connected otherwise you will get a C.E.L.

this is what it is: http://i197.photobucket.com/albums/aa208/Pilot_Reuben/Single%20Conversion/conversion15.jpg (thanks to reuben )

[dubbedup]

its for a wrx and this is maybe why i have not seen any green solinoid.....

[chrisjunkie]

nope as far as i know it is on all of them. I got one with my intake manifold and that was off a wrx
