In prep of total vac and air hose replacement I noticed nothing matches up on the canister. Going from left to right on the diagram (1,2,3,4) my #1 (purge signal) goes to the fuel tank, not the EGR. #2 (PCV purge ) goes to purge solenoid. # 3 and 4 are “T” connected and run to a multi vacuum connector on the cylinder head. WTF? I do have excessive fumes in cab. Just a PO fuck up or does this make sense for a reason?

Mine doesn't have a tube. I think it is supposed to drain. I have an evap canister from a CJ (a couple years older), and there is just a filter on the bottom.
 
The purge signal port on the evap canister... I would think this is just a signal to sense vacuum. Is this supposed to hold vacuum? Using a vacuum pump, I can suck on this all day. I believe this is causing me to have too little vacuum to operate my EGR valve.
