95 E320 vacuum line question

[sasjzl]

Hi all,

Could someone help me remember where these 4 vacuum lines hook up to?
If you go to this URL you see two white vacuum lines coming the box in the vicinity of the exhaust cam. I have pictures showing me where they go but not what they hook up with.

In the second picture I am trying to figure out what hooks up to that dashpot and also the rubber vacuum line that is right next to the throttle body that you cannot really see in this picture.

Thanks very much,

EGR valve ontop of exhaust manifold thru spark plug area of valve cover.

I assume the ones in the first picture at the front of the cam. left to front EGR and right to rear EGR as veied in photo.

White single plastic line is feed to both EGR and AIR SOV valves. From their, one goes to the EGR and the other to the AIR operating valve.
Easy to mix up that connector, so be careful.

Thanks guys. Bear with me though.

Looking at the top picture. I am pretty confident about the the passenger side vacuum line going to the valve that is between the air pump and the engine. That is the 'left egr'. The drivers side line is that I am not sure about. I must have misplaced an additional vacuum line because as it is it is too short to go attach to anything past the front of the engine, just below the camshaft electronic thing. I see two places that this might go to. One, the silver egr valve looking pipe that sits on top of the front of the fuel rail that you can clearly see in the bottom picture. OR does it go to a blue connector further on the drivers side that splits off to two seperate lines that go deep below the intake manifold.

The next thing that I should have been smart enough to take a picture of is the u-shaped black rubber line that is between the fuel rail and the throttle body.

I took alot of pictures, I swear, I just did not take all that I needed to.

Thanks very much,

I guess where you are confusing me is left EGR , etc.

There is only 1 EGR valve and it is at the right/rear of the engine ..that line connects to the SOV valve . The other SOV [ piggy-backed on the EGR one] feeds the AIR valve. That is the one I think you are referring to as an EGR valve. That is ahead of the EGR , closer to the SOV, and it is inthe pipe from the AIR pump. And both of those SOVs [ Switch Over Valves} are fed with the single /white plastic line.
The U shaped rubber line on the engine/left side goes down to the black plastic line that is way down on the left/front frame rail.
And the Fuel pressure regulator [on top of the fuelrail ] goes to one side of the Y connector.
You want the vac schematic????????

That would be great to have the diagram.

Thanks,

It will take a while..I have to scan it and then download it to a jpg.
