Hi

I'm trying to figure out the vacuum lines that my Fiesta ST has:

After the TB I see two vacuum lines:

One goes to the back right and it seems it finished in the brake fluids deposit.

The second one is cover with some plastic stuff and don't know where it goes

The third one before the TB and since I have the K&N is the breather hose, but not sure what is the function of this hose.


Any help is appreciated.

Thanks

You need to put pics up to describe!
The one going to the master cylinder isn't a vacuum hose it's the fluid line to the clutch slave cylinder.

Hi Dave,

Yes sorry here is the picture and in red square are the 3 hoses I mentioned before.




Thanks

And here is the second picture with the hose from the induction kit

Hi Dave,

Thank you for the answer, so you recommend to use a breather filter in this hose? Am I correct?

Also could you rephrase the words "blanck off the inlet pipe to your air filter" English is not my mother language and I cannot find the meaning of "blacnk off" is like block something, perhaps ?

I think that was a typing error from Dave there!

Yes he means "blank" or "block"

what size breather is the best to use then mate with an !?
12mm 15mm or 18mm

i have fitted a oil breather on mine andhave a K&N blanked the breather hole in the filter. heres a pic of what it looks like.

1. Oil breather/ventalation filter
2. Ecotek valve
3. vaccum line to brake servo
4. blank bung on K&N, (where oil breather pipe would have gone to)

yeah mine goes back into the GGR induction via that pipe...
You're stuffed either way because you either let the hot air out of the breather filter into the engine bay or via the pipe back into the throttle and my engine bay is hot enough with a 4-1 Milltek Manifold with no heatshield LOL!

what does the ecotek valve do?
