Does anyone know what this thing is, its right over my battery from the driver side, also, where does its hose connect to??? (the picture might be hard to see, but hopefully someone would know what ball IM talking about) Here are two pictures, the first one is hard to tell, but i'll point it out, the second is the loose hose from the wierd ball.

 

Heres the second picture

 

thats the orb of power

or more commonly known as the vacuum canister (it stores vacuum at idle and such so you can use your brakes and **** at low rpm's)

 

Do u know where I can reconnect it? Because I found it lose

 

there should be vacuum lines going to it, if not look around for them

 

in the second picture, dats what I found, I have no idea where it goes.

 

look on the back of your intake manifold is there a vacuum line going back there?

 

I cannot tell, where is the back of my intake manifold located in my 3.1L?

 

i mean the intake plenum, but when you open your hood and look at your motor the thing that the air intake goes into, at the back of there should be a t fitting. check for that

 

Ill take a picture because at the back, i see something dat is not covered... ill take a pic in a few moments, thanks

 

no problem. lets see that pic and i can help ya out a bit more

 

This is the best my camera phone can do.

 

is that an electrical connection attached to it?

to my knowledge theres not a vacuum connection on the back of the manifold, its hte plenum

 

I took more shots of my 3.1L, nevermind, the digital camera took my pix too high, in order words, files are too big to upload here

 

In the picture there is a spot were the hose from the power booster goes to and then another vacuume line goes on the other side. It connects to that but you need a part its not a T fitting it has some function to it but i dont know the name just what it looks like. Thats were the Vac fitting will go to. You just need the missing part.

 

It is a check valve, should be near the wiper motor, connects the vacuum hose from the plenum to the hose to the orb (and cruise if you have it), and there is a tee connection on it that connects to the hose that goes to your heater a/c controls. Mine looks kinda white, but I think it is just because of how old it is.

 

My vacuum line should be located by the master cylinder?
I will retake a picture again and see if i can find anything

 

in this pictures, what is dat thing called, where i am pointing at it

 

That is the Schreader valve on the fuel rail. That is where you would attach a fuel pressure gauge to check your fuel pressure.

That small hose on the tee on the back of the plenum (your arrow crosses it) is where the hose to the check valve should go, and then from the check valve to the orb.

Looks like there is a hard plastic line on the tee in your photo? Where does that go? Also where does that other hose to the right of your arrow go? (you've got a 3.1, my 2.8 doesn't have that second hose all by itself in the back of the plenum)

 

i dont think mines has dat part, I can take a picture of dat area and u can be the judge of dat

 

?

 

when I replaced my battery tray, I broke this and have never installed it back.

I can still use all my vac options just fine.

 

I still dont have a clue where dat vacuum hose goes in my 3.1L

 

it goes to the check valve as shown in the picture.

 

THE ORB OF POWER!!!!!!! :hail:

 

I triple checked that area in the picture and I do not see the check valve... I'll take a better picture of it when I get a chance, my camera phone is a piece of crap when it comes to taking digital pictures...

 

Someone may have taken it off at one point in your cars life. Just go to the GM dealer they run like 5 dollars.

 

Ill take a picture again and see if i can get an idea where it should be

 

since you are doing this anyway you might as well replace those lines. napa sells "windshield washer hose" that is the same as vaccume line stuff.

here is a photo i made (real board today)

 

try that phot one more time

 

My vaccums line are really different, from the orb, it connects to this thing.

And notice, u'll see a T connector, I figured out dat they just put an extra vaccum hose. So, do I really need a check valve in my case. Since my org connects to dat thingy.

 

Heres dat same picture, but with some info.

 

The "thingy" is your cruise control servo.
Look at Xophertony's drawing (nice job) and you'll see how the hoses and tees etc. should run.

 

ON dat T, the orb should connect to the cruise control... I just capped the top part of the T.

 

thanks, i spent like ten minutes on it.

i capped my tee for a long time. eventualy replaced the line and used one ong hose w/o the need for a tee. permantly finishing my cc delete.
