all info is in regards to a 2000 Acura Integra Type R:

i'm trying to piece together my EVAP system, but i'm stuck with the last part.

in the following diagram, you can see a drawing of an evap canister. my canister actually does not look like this one, but i'll use it for reference. i have a port on the container labeled "5/8". this is my problem area. on my car, this port sticks straight up, as opposed to going to the side, along with the small one:



but, anyway: from the service manuals, it would seem that the 5/8" hose goes to a metal hard line. from the hard line it shows it goes to a solenoid near the gas tank. note that it also shows it going to a horizontal port on that solenoid:



first, how does a 5/8" hose fit on the stock, 1/4" hard line? or is the stock hard line 5/8" also? mine is gone, so i have no reference.
second. when i look under my car, the rear solenoid is all hooked up to the proper vacuum lines (i think. they don't look disturbed) except for one of the "ports" on a small, white, 1/8" vacuum "T" that is here:



which, as you can see, is on TOP of the solenoid, not on the side as shown in the second illustration. sorry no pics yet. i didn't have my camera.

anyway, do any of you guys know how this is all supposed to be routed? i'm looking for pics, info, etc. i'll post pics up of the rear solenoid tomorrow.

from what it looks like: the 5/8" hose goes to whatever size the hard line under the car was.. then it went down to a 1/8" vacuum line. that makes no sense to me.

 

okay. here are the other pictures. description:

1. this is the port where the service manual shows my charcoal canister should attach. as you can see, it loops around and connects to a quick-disconnect fitting. wtf? i THINK that quick-disconnect fitting is the fuel return line (also, according to the service manual), but i'm not 100% sure. i can't see where it goes. somewhere towards the top of the fuel tank. if it DOES go to the top of the tank, then it's not connected anymore, nor attached to a line that goes to the front of the car (just out of the camera views in pics one and three). confused yet? sorry.
2. this is where the solenoid connects to what i THINK is the fuel return line (?). if this is the return line, it is not being used.. and i don't know what to connect the solenoid to instead.
3. this is the 1/4" vacuum "t" that is open to atmosphere. it's the ONLY open spot that i can see (other than the "fuel return line"). so, it's the only place i can think that the canister, in the engine bay, would go.. but how would a 5/8" hose end up as a 1/4" vacuum line??!!

i have never dealt with the purge system before.. i'm so lost.

if you guys have any clue of what in hell i need to do, please let me know. this is very frustrating
