what is this hose?

[tstrahonja]

there is a black rubber hose going from the middle of intake manifold, down side( arrow 1) to the engine( arrow 2)...
mine was completely cut and i was loosing boost thru that hose...i took off the destroyed hose and blocked its hole on the intake manifold so now it boosts fine...what is that hose for?

Looks like the vac line for the DV so yes it would have had a boost leak thus causing boost loss.

What engine is that from? It aint a standard ibiza intake manifold as they dont have a vac port on the front like that and what the hell is that this sat on the injector rail?

lol. i thought it looked slightly odd for a Cupra

 

[tstrahonja]

it is a standard(remapped) AQX engine but there might be some difference due to i am from Croatia and i do have steering wheel on opposite side...
it has LPG
and its not s DV vac line, DV vac line goes to DV and its located much more to the side of intake, not in the middle like this and DV hose goes to DV and this hose is 20cm long and goes directly to engine under the intake.
on the picture its not really visible cuz that hose is located on the intake but on the down side so its not vissible...arrow 2 should be pointing under the intake, to the engine and not that vac line

Havent got a clue then as none of the cupras over here have any vac line there on the intake manifold

 

[Reuvers]

it has nothing to do with the steering wheel being on the other side either. Mine is as well, and your engine looks very strange to me as well.

whatever that thing is on the fuel rail I don't know, and as said the vac port on the inlet is new to me as well

 

[tstrahonja]

stuff on the fuel rail are LPG injectors...

here is a pic i found on ebay...i hope someone will know what this is

that nipple connects to a T piece, and PCV valve.

Look up the thread on where to plug in your catch tank. That describes it.

If you were to put a catch tank on you block off that port.

 

[Myki da Pyki]

As reuvers said the nipple underneath the inlet manifold is for the pcv valve, it wont connect to the nipple you've label "arrow 2" tho as that would just be joined back up to the manifold.

Did you buy that manifold for the car or was it already on it?

Looks like a fuel filter in the engine bay on the fuel rail as well lol

It was on the car...

As mentioned be4, arrow 2 does not point to vac line..it is suposed to point underneath the intake manifold..

Yes you are right, it does connect to a T piece and to PCV...so what is the purpose of that hose?
I assume oil passes thru it and is being send to the intake manifold making cylinder head dirty...

 

[s1l3nc3r]

could the hose in the middle of the mani not of been somthing to do with the n249 can see the resistor set up but where ours goes to the underneth of the mani on the left there doesnt seem to be room on this one so could be relocated to the middle...just a thought...???
