Vac line diagram
Im just wondering what you guy have done for your vac lines and crankcase ventalaton.
Ive gotta take my inlet manifold off soon, so i thought i would get opinions on how mine is setup and hear what others have done too. im going to use some silicone hose this time too! (i should of the 1st time)
this is basicly how mine is now.. slightly different but the best the brain remembers.

RED = vac lines
BLUE = fuel
GREEN = crankcase ventilation
all unused vac nipples are capped (not shown)
ive kept the pressure sensor so my std boost gague works (which it does with a 5v power source) and the charchol canister so that a (not too hard) look under the bonnet dosent scream ive got no emmisions gear at all

Adsy,
dont ever use the silicon stuff for vacuum lines, it is crap it sucks closed and blow up like a ballon under boost,
i did a test the other week,
took a piece of 1/4" id blue silicon hose and a 1/4" id -4 braided hose, the pressure difference they read was 4psi!! so if you use one on your map sensor you will be reading 4psi less than what the motor is getting!!

yes -4 rubber hose (1/4" ID) covered with a stainless braid, that stuff is eaisly avaliable down here, looks 400 times better than the silicon stuff as well,
the stuff i had was 1/4" ID and had a very stiff thick wall but it still managed to swell and suck closed,
ill get some pics of my engine bay with the new braided vac lines,

can you get a reinfoced type of silicon hose??
im not too happy with the rubber thats on there now it may of just been a bad batch though, but it has aged alot and it's very low mileage and 6 months old.
Also what about the silicon hose that comes with things like turbosmart boost contollers?? ive seen two types.. the red stuff (looks reinforeced, is very think and heavy duty looking) and the plain looking clear stuff, are they suppling stuff that should be replaced?
Any one want to comment on the digaram?

adsy,
not sure if you can get reinforced stuff or not, the turbosmart stuff is really really stiff and seems ok, its the ***** blue and red stuff that is no good,

you guys tell me what you want and ill get something happening,
the only problem with the braided stuff is you need a 1/4" vacuum point to put it onto!! i drilled and tapped my UIM with a 1/8bsp tap and screwed in fittings, looks hot and works a treat as all the fittings are anodized blue and red.

What size is the nipple for the MAP sensor on the back of the ECU?
You should have 2 sources, right? One un-interrupted to the MAP sensor and the other one for the boost gauge and BOV, or am I mistaken?
I wouldn't need very much line, around 2-2.5 meters should be plenty. Then, I'll need to understand more on how they connect to the BOV, MAP, and boost gauge.
