Help identifying fuel lines/what goes to the canister! Options

[aspen]

Working on the swap. My friends decided to not follow my advice and label things as they took them off, as such I've got three things I don't really know what they do in the engine bay.

All are lines that originate near the canister.
There's the return line, which we're pretty sure about, the short little stub that goes to the canister, and then one other line. It's this one we're unsure where it goes.

Does the Canister have two connections that aren't to the EVAP VSV?

Help please?

There are 3 vac lines on the BEAMS. One goes from the throttle body to the fuel pressure regulator, one goes from the TB to the VSV, then the third goes from the VSV to the charcoal canister. The fuel return lines comes off of the FPR and goes to a hard line on the firewall. Then there's the main fuel line from the fuel filter to the fuel rail but I do t think you were asking about that one. I'd have a look at my BEAMS and take some pictures for you but my car is a couple of hours away. If I recall correctly, there is a second line on the charcoal canister but I can't remember right now.

Yeah, that's the issue, there's 4 hardlines. 1 to fuel send. 1 for fuel return, one for the bottom of the carbon canister, and one that I don't know where it goes.

Quick edit here, we got it. One of them is secretly the EVAP canister outlet.

And hence, it runs.
