Eaton Vacuum setup

[tjl006]

The vacuum set up has been covered before for eaton swaps but I thought some pictures may be helpful.

The bottom nipple on the back of the eaton is vacuum/boost refrence, meaning this port sees both vacuum and boost. An elbow with three outlets is attached, this is a reused part from the factory vacuum set up. The frps, boost bypass and lower port on the fuel vapor canistor are attached to this nipple.

The large vacuum port is capped on the back of the eaton. The top nipple( the one with nothing attached to it in the picture) is attached to the larger hose coming from the fuel vapor canistor.

The nipple on the plenum is atached to the large vacuum line that goes to the brake booster, hvac system and vacuum canistor. This large vacuum line is attached to a swivling tee on the firewall.

Note: There is also another port on the bottom of the cobra intake manifold. This port is plugged when setting up an eaton with breathers and a deelted egr

nice job. that was one of the more confusing parts of the swap

Nice write-up :up:

The pics attached shows the other port not discussed in post 1.

This port is hooked up to the DFPE Valve (Fuel Vapor Canistor) Top Fitting.
(The line that attached underneath the TB on the Stock Upper Intake.)

Could I see a picture of said plugged hole on bottom of intake? I hooked up a PCV on the drivers side head to the capped one in your picture on Bawazirs car and a hose from the passenger side head to the intake piping right before the TB. All seems to work smoothly.

When I originally hooked mine up like that it made some foul hissing noises and the hoses were about to collapse. :confused:

The hole is on the underside of the cobra lower intake. It is just a single tapped hole. Orginaly on the cobra there was a vacuum/boost line connected to it.

I ran into the same issue with collapse. I made a custom bent piece of 1/2" emt conduit pipe, it was a perfect fit into a rubber 90 going into the blower and a straight 2" rubber hose on the PCV 90.

Gotta use rigid or semi-rigid tubing like the factory uses.

I'll post pics tomorrow of how Bob hooked it up, pretty cool i have vacuum, my boost gauge read 20 for vacuum

[bawazir]

Here is how my PCV is hooked up.

all I see is an empty box

[justbob]

I see it. You still haven't painted that yet? LOL Atleast wrap some wire loom or something! Looks like a home depot car with that and the fence post mod.:lol:

[SmokdMercRauder]

yea...blank for me too

[FordNut]

yea...blank for me too

Virtually every pic that bawazir posts is like that for me.

[justbob]

Really? Let me see if I can just post the link for you.

That works, at least it takes me to youtube. I get a youtube popup nag screen about browser updates but it really doesn't matter since I'm on dialup and can't watch videos or download large pics anyway.

according to this post, the fuel rail pressure sensor and vapor canistor are supposed to get vacuum and boost. Why do the need to receive boost and is it absolutely necessary? right now my canistor lines and my frps are both getting vacuum only and all seems well. Whats the big deal?

[justbob]

Not sure about the canister, but hooking up the FRPS to boost is so it can sense boost so i'm told. I didn't hook mine up to boost for a year or so and noticed no change.
