Yes, Item 4 is exactly what I was talking about. The diagram showed the tee in the wrong place, though. Details.. I ended up jerry rigging a new connection because both the tee and all three ends of the hoses (which are plastic or PVC), with rubber hose, a brass step down, and hose clamp.
Since it's just a breather hose, it just needs to direct air flow, so I'm really not worried about it being perfect, just hold together. Now the jeep still won't start, but it's throwing codes for the TPS, the Idle Air Control Valve, and the Engine Coolant Temp Sensor.
Already replaced the TPS, just got the IACV and Coolant Sensor, so we'll see how it goes.
Thanks again folks!
