Here's my setup,

Fuel Rails from Zak @ Mocom Racing:

 

abelutly spot on thanks mate, waw your set up looks nuts, did you build it yourself or did you buy those hoses as a cit? id love to have mine looking like that but i probably couldnt afford it.

 

Built it all myself mate. I have a local supplier of hoses and fittings so that helps.

 

about how much you think that set you back £? iv just looked again at mine, theirs three metal pipe ends, one is feed are both the others return pipes? what do i do with the third pipe that seems to return to tank, do i just leav it unconected,

you should build these as a kit and sell em haha. . . . . .

 

Ok 1 is feed, 1 is return the other is a breather that's routed via the carbon canister.

The rails were £130, the braided hoses and Goodridge fittings were about £250 i think, it was 3 years ago so cant remember. Plus reg.

All in including swirl pot, lines, fittings, injectors (740cc) FPR, and both pumps (walbro and bosch 044) I don't think I got much change from £1500

 

aaa ok makes sens, you now that litle solenoid like thing under the inlet, is that needed? cuse a breather gose to that and a vacume hose for the fuel presure regulator gose from the top of the inlet to the regulator, im geting the jist of this slowly, soz, haha

 

I binned everything breather wise forward of the bulkhead pipes. I've put a piece of vacuum hose with a 1 way vlave in it that vents down to the chassis rail. I've left the solenoid valve wired up in case it threw up a Check Engine Light.

 

a right, have you got any pictures of it from like further away, showing mor of the system , i think i uderstand it now just want to check, ha

cheers far all the help, have you noticed any diffrence syns doing this mod?

 

do as earch for a guy called mef, he converted my fuel rails to -6an ends & supplied me with the t pieces, elbows & the braided lines for £275

Why don't you just run reverse flow??? It's alot cheaper than the parallel setup and fine for over 400bhp, it might be an option for you mate? Where the OE fuel pressure regulator is positioned becomes your INLET to the fuel rails instead of the OUTLET. You can only do this if you have an aftermarket fuel pressure regulator. I've known scooby's to run over 400bhp with this setup and no problems. Hope this helps mate.

 

so i can get rid of the carbon canister aswel, cus iv brought a breather catch tank, it would be a good place to mount it ai. whats the valve you put on the fuel line breather?

iv got some hosings and t peases so guna start it tonight i hope.

cheers.

 

The Valve I used for the breather was in amongst the Canister Hosing. It's arrowed so you know which way "flow" goes through it.
