AE101 4agze vacuum lines help

[greyae92]

I have a 4agze, it didn't come with any vacuum lines, no hard lines, no soft lines. I don't know where anything plugs into. If someone could shoot me some pics and label what goes where I'd really appreciate it. I can't seem to find any reliable pics of things and a factory diagram gives me little help since I don't have most of the lines they show. Thanks!!! You can post of email me greyae92@yahoo.com

If I could find out exactly where the map sensor connects to and where the FPR vacuum hooks to that would be enough for me to get the car running

On the intake manifold next to the cold start injector there is a nipple in the manifold Tee this to the fuel pressure regulator and the bottom nipple on the air bypass valve. On the back of the manifold there is a screw in vacuum tree and connect the map sensor to that.

The only other connection I see on the intake manifold itself is the inlet air temp sensor

This nipple with the blue hose on it is what you Tee the FPR and ABV to and boost gauge if you have one:




This is for the MAP sensor at the back of the manifold, air temp is on the side:

Thank you!! That explains a lot, I don't have that vacuum tree, I just thought it was a bolt hole for mounting something and it's almost non visible with the wire harness over it. Next question, can I use a vacuum tree off of a 4age in place of that or do I need a 4agze one?

[jdm86gtz]

Yeah 4AGE one will work, just block the other 2 nipples on it or take your boost gauge supply from one of them.

Exactly what I needed to hear! Thanks for the help
