See the last cyan colored vac line coming off the Dynamic Chamber and labeled as leading to the "air bleed socket." Well where is the air bleed socket?

I've got everything hooked up, just stumped by this one, and the Haynes manual is little to no help.

The only other place that a vaccuum line could go is to a tube on the lower intake manifold where the Sub Zero Assist fluid is injected. I capped off the vac line as well as the line to the sub zero tank. I'm thinking that the vac line went to this, I even have a molded brittle leftover vac line which seems to fit....just curious if anyone knows.

right on.

 

the Air Bleed Sockets are right inside the center housing where the fuel injectors are at. Get that vacuum line back on there or the fuel spray pattern might go whacky

 

F- me so I think I know what you are talking about...I thought it was something that helped the sub-zero assist but maybe not...here is a pic...is that the air bleed socket right there above the two middle intake holes?

It looks like I can probably get to that without removing the upper intake, since everything is on the car now, looking real pretty. Update coming soon.






Right on.

 

While you're at it.... CLEAN THAT MESS UP!!..

 

Right on!

 

Mound.... in that photo of the lower manifold.. see in the center the nipple for the vacuum hose that sticking straight up? Thats for the air bleed sockets...if you blow air into that you will feel air coming out from that circle with the horizontal shaped slot which is right above the 2 primary intake ports in the center. The airbleed sockets themselves are in the center rotor housing underneath the fuel injectors.

 

Yes, it's the nipple on the intake. Only the center hole is for the Sub Zero system. The outer, smaller, passages lead to the injector receptacles. When you installed the injectors you probably noticed the "inserts" in the holes: they are the air bleed sockets.

On a side note: I had always assumed the air bleeds were to help keep the pressure across the injectors closer to the regulated fuel pressure by introducing atmospheric pressure below the injectors, instead of having 28 psi above the injector and manifold vacuum below them. But I've read the air and the air bleed sockets are actually to help with fuel atomization.

Unless you know a mechanically inclined 3 rear old, you'll probably not be able to get a hand in to reach the nipple. But just loosening, not removing, the upper manifold/chamber as an assembly should give you room.

Edit: RacerX7fb is correct. My memory failed me. The Sub Zero is injected straight into the manifold tubes.

 

OK, well I see my error now...I assumed that the vaccum line assisted the cold start assist, but in hindsight that doesn't make sense.

FJ, looking at some after photos that I have after installing the intake this weekend, I think you are right, It looks like I just have to loosen the upper intake to get some clearance to get a hand or pliers on the nipple to remove the cap and put a line on.

Thanks for the help guys. Web update on my project coming tonight.

Right on!

 

I got it on...I did loosen the upper intake complete in order to lift it off...I was able to use some long needlenose to remove the cap, and I put a little WD-40 in the new hose to help slide it on...wasn't too bad...just a little patience.

Right on...thanks for the help.
