Robert, the line from the filter neck is a vent that allows fuel to flow freely when fueling. Don't mess with this, it is the source of agony for those whose have gone awry.

B should be your tank vent. Don't block that off or you will have problems. A should be the filler neck vent line, see if you can trace it to the valve housing at the top of the fill neck

E should run back to the intake manifold and insert where the AOS connection is located. Pop off your inner panels and connect the dots. You may just be able to tell by the hose diameter.

This would mean that the system is set up as follows - 2 vents come into the canister, and when the purge valve opens the vapors flow into the purge valve via C to mix with neck overflow from D and then onto the intake via E.

I think the most important thing here is to confirm that the lines running into the canister are vent lines and to not block them off. I would just Y them back into the purge valve via C. Theoretically you could remove the purge valve assembly and Y everything together but I'm not sure what that would do in terms of unmetered fuel entering the system and it worked likely throw a CEL if you disconnect the wiring harness for those two solenoids.

I should say that I have no idea if any of this is correct, I'm guessing based on my (limited) knowledge of what should be there. This project is on my build list but I probably won't get there soon, but when I do I'll let you know.
