I need some help with vacuum lines. The Haynes manual is relatively worthless for this. At the back of the engine bay on the firewall should be a small flange with two pipes on it. Four vacuum tubes are attached to the pipes, and go to different areas in the engine bay. I need to know which tubes go where, I'm missing two and I have a feeling this is the cause for my wacked out idle and cruise control. Pictures would be the best way to show me, if at all possible.

Here's a picture of the said flange:

 

Interesting how my 95 F22B1 doesn't have the vacuum fixutures that high. I shall have to inspect my mother's 94 F22B1 auto tomorrow...

 

the top one goes to the evap canister under your cruise control diaphram.
the bottom one goes under the stock intake into a box near the air filter.
these both come from the intake manifold.

 

Heh, I think I'd need pics, especially since one of the tubes leads to an intake that doesn't exist anymore...

Ok dude. Lets start at the two nipples on your intake manifold. From there the lines go to the metal rod attached to your firewall. The TOP LINE goes to the evap canister under your cruise control diaphram.

THE BOTTOM LINE goes through a series of check valves and runs along the intake and ends up plugging into a vacuum canister under your stock intake. I looked at a stock accord for this.
