2.2 swap, fuel vent line to purge control?

[musubk]

I'm near wrapping up my EJ swap, EJ22 from a 1990 Legacy into a 1986 BRAT. I was plumbing the fuel system today. I know what to do with the fuel delivery and return, but I'm confused about the vent from the tank that goes to the charcoal canister and the purge control solenoid. The EA81 didn't have this line, so I'm not sure where on the fuel tank I should take this out of. The tank has:

 

2 lines on the forward, lower part of the tank. These are fuel feed and return.

1 big hose on the passenger side for the filler neck, and around a half inch hose next to that for the filler vent.

2 small nipples on the rear passenger side that loop through some kind of device inside the fender near the taillight. I assume this is the vent system for the EA81.

 

So I figure I want to use one of those two small lines that were used for the ?vent? on the EA81 into the rear fender. To which of those two nipples should I attach my vent line and run to the engine bay? Does it matter which one I use? Then just cap off the other one? Or maybe use a 'T' fitting to feed both of them into the vent line?

 

I know the car will run without this at all but I'd rather have it hooked up.

I think I understand this now... the vent line I'm looking for comes out of that canister in the fender. I was confused because I only saw two lines coming out in the engine bay. The third - the factory return line - comes out near the transmission tunnel instead. So I will hook up the vent line (smaller of the two coming out near the driver's strut tower) to my EJ22 canister. Feed and return lines I'm just running new hose.
