Question Help the idiot - Vapor Lines

So I do accounting by day and am learning truck by night. I can't figure out the purpose & where the vapor lines are supposed to be attached. Or do I need them if my tank is EEC?

I bought the truck already torn down, but I don't think having extra means I'm more efficient.

In reference to the below pdf, Where are the different ends supposed to connect, or do they function like a plumbing P-trap to catch/prevent vapors?

It's a 1972 Chevy C10 402ci, if that helps.

A - Goes to Fuel Pump
B & C - Are buddies/connected by hose
D - no idea...

Should #5 be vertical or horizontal?
