I'm trying to figure out where a few of my hoses go before I put my engine back into the car...

First off, what hose goes into the nipple coming out of the rear housing? For now I've got it connected to one of the nipples on the throttle body but I don't even remember disconnecting any with clamps on either of those nipples...

Second, there's a half-inch nipple that goes into the lower-intake manifold, that I *think* loops around and connects to another nipple of the same size but I'm not sure... when I do loop it around, it looks just a little bit kinked but not too terribly badly...

Third, there's a hose that goes into the BAC (I think), and I'm pretty sure it's supposed to be one of the hoses that goes to the air intake...but I'm not totally sure I'm using the right hose... even if that's true, I don't remember where the OTHER intake hose goes...

There's some sort of hole on top of what I think's the BAC, and I'm not so sure exactly what goes there, if anything...

Finally, how many nipples should be left empty until I get the engine IN the car? Two or three, maybe?

The vacuum hose diagram is kind of vague for certain parts of the engine...

you forgot one major thing, model and series car.

oh yeah... 89 GTU

One I forgot... I'm trying to reinstall the oil filler pipe hose, but the nipple on the purge control valve is WAY too short to even try that... can I leave it off without causing a vacuum leak?

And one of the hoses that goes onto one of the solenoids doesn't seem to have a corresponding hose at all... I wonder if it has one in the engine bay but not on the engine?

My idle is already bad enough without any new vacuum leaks...hehe

the first one sounds the return hose from the heater core.

According to the manual it's an "evaporation hose" but it doesn't tell me where it goes at all...

There's two more vacuum hoses that I'm trying to account for...

One is on the manifold side... it's one of the two vacuum hose nipples that form a V-shape. I assume one of them goes to the pressure sensor, but where in the world does the other one go to? I can't find any other hoses at all.

Also, I can't find the hose that goes to one of the solenoid valves... I thought it was supposed to loop around and connect to something else nearby, but I can't find any place for it to go at all...

That is, unless I've got one of the other hoses going to where this one is supposed to go...
