Proper Charcoal Canister Routing

[C6c6s]

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?

I’m having to do a complete overhaul on all of my vacuum hoses to my 89 Jeep YJ (2.5L). I reviewed the diagram you posted. Mind if I ask where I could get a copy?

Sorry for the late response. I found that right in my Haynes manual.

Hi, is there a tube supposed to connect to the bottom of the canister?

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.

Great stuff. Thanks for confirming.
