What lines go to this and where do they go?



Maybe if someone has a vacuum diagram I can figure it out. I saved one and I don't remember where I saved it.

 

I haven't seen that before. what year? I'll look it up on VIDA

 

It was on my 94. I don't remember if the 95 block had it or not. If I don't need it, I'm going to take it off. I'm pretty sure nipple #1 goes to the vac tree, since the hose was "shaped" right to it. #2, I'm not sure where it goes.

 

I have that on my 94. It's your PTC nipple hose.

 

my 95 doesnt have it ive only seen it on a few 94s

 

For the PTC? So the PTC vac line goes to that and then to the intake manifold?

 

I'm taking it off then. I already have the PTC, if that's what it's for, going directly from the PTC to the intake manifold. Well, now I can take that ugly thing off that blocking the view of my pretty powder coat.

 

Take it off. I was questioning why they even did it. I kind of like it how how it's not fiddliing all over the place. but yeah. I can get better pictures if you would like?

 

Is it that though? The vac line from your PTC goes to that then to your vac tree?

 

Yep, that's all it is.

 

lol. What a stupid idea. Seeing as how I already have the PTC vacuum line routed there no reason for that.

 

Yeah, cause you have an newer engine right? That one is designed to work with the manifold paired together with that engine. IIRC, 95+'s have the nipple on the side of the Intake Manifold and the tube that goes with it wires though with the main PTC hose, while some of them don't. I don't have the nipple on the side of my Intake Manifold.

 

Yeah, my manifold has the nipple on the side of it. My previous manifold did not.

 

Yep, that's what the little metal thing is for.

 

Excuse my ignorance but what is PTC?
