From that description I believe you are talking about the BOV (Blow off Valve) recirculation tube. This is the tube coming off of the BOV and running back into the intake. You are going to need this if you are running the stock MAS. (Mas Air Sensor)

Another possibility is the rubber hose going to the release valve on the valve cover. If you are missing this there will be a metal nipple uncovered on the valve cover. You can find this on the far left side (passenger side) of the valve cover. This however is not necessarily needed. But you will need to get a breather filter for that nipple in the worst case and in the best case get a catch can with breather filter. This will keep the engine bay clean from the oil blowing thru from the crank case pressure. Also if you do this cap the nipple on the intake.

well i have the bov hose from what ive researched . Seems to be a small rubber hose and its part of the two rubber hoses on the plug thats on the top of the mafs. The intake pipe coming off the turbo to the smic is the one im talking about. Theres a little bent pipe coming up, it has a rubber hosebut i dont know where it goes and the waste gate vaccum line is missing. I looked at vfaq and saw this little thing that runs a T for the vaccum lines to the waste gate and compressor (intake) pipe, i hope i described it ok...

WTF Punctuation please! It is hard for me to read and understand that.

sorry is that better?

The nipple coming off of the pipe on the turbo is the nipple that carries boost/vacuum to the boost solenoid or boost controller. This of course depending on what you have. Without this line you have one hell of a leak and the car will run horrible. The boost solenoid is what controls boost on a stock car. This is a black cylinder looking device that can be found up near the air canistor. Usually between the head light and air canistor.

ok its the manual boost controller i think is whats missing . According to this its the wastegate signal hose is what im talking about.
The boost control solenoid is there with two hoses from there, one goes right to the mafs plug, the other is the one im talking about that is free with nothing to connect to . My manual boost controller and vaccum lines to the wastegate signal hose and waste gate are missing, what do i need and whats the right way to route it?

 

[91gsxdsm]

ok actually i find that the waste gate is connected to the nipple on the compressor pipe. So where does the second vaccum line from the boost controller solenoid go to? What about the sending unit on the fuel tank what is the little fuel filter for and why isnt it filling with gas if the fuel pump is working?

 

[JDNSBR]

The vaccum will go from the nipple to wastegate. However there will be a T in the line and the T will have a line going to the boost solenoid. (sp?)....I miss spell check.

 

[91gsxdsm]

ok thank you . I will get a T fitting and connect those lines correctly and let you know how it goes providing i can figure this gas out. Does anyone have any idea on the gas?

 

[AWDPetmitsu]

What's your question on the gas?? You never gave details.

 

[91gsxdsm]

The fuel pump in the car is working, but the car isnt cranking, but will crank when gas is poured into intake , theres a little fuel filter on the gas tank, its not filling up with any gas , i havent checked to see if the fuel filter under the hood has gas, i will check that when i get home from school but what causes the fuel filter on the gas tank which is right next to the fuel pump not fill up?
