There is a vacuum tree

On the manifold behind the throttle body. There should be one hose connection just capped off that you can use.

Hmmm, im not seeing that!

I see a blue cap next to the FPR which I believe is on the fuel rail? This cant be what your talking about?

How about the brake booster line? I suspect you could use that!

 

[DonM]

Maybe? Im not sure, that's why im asking.

I think both PCV and brake booster line would be good... why not try at least?

 

[DonM]

I'll try useing the PCV hose Thanks!

Oprea House, Im either blind or your thinking of a 1st generation Ex? Im not seeing what you describe! Which has me a bit concerned. If you are correct, then I missing the cap or the hose? Although im not seeing anything that might be out of place, or missing. Everything looks to be normal?

Ive looked at the the Vacuum Diagrams in the Chilton guide and diagrams that have been posted here, none of which really explain much. Maybe some one has a pic of their engine?

Thanks for the help guys

On a first generation the vacuum cluster is on the rear right side of the upper intake manifold. It will have several openings. Some with hoses attached and some capped off. You could use that if it is the same on your '95.
