EVAP System Inspection Port/Purge Solenoid Harness

The EVAP Duty Cycle Purge Soloenoid on the 50 State Emissions version of the 2003 Sport 4.0L seems to be something one cannot purchase. It is not listed by number at all in the 2003 Parts List, but it is mentioned by name. (HARNESS. Vacuum Canister Purge.)

I have found one (Mopar PN 04854134AC) here. It looks sort of like mine, but one of my lines is a plastic tube seemingly heat-shrunk to a hard line. I think this is why it is not available by itself. Perhaps I need the hard line part number and the permanently attached harness/port setup would be included? Don't know. The FSM and Parts List are worthless. I just cannot find this harness anywhere.

Here are pics of the one above as well as mine.

I am sure mine is fine. I need the stupid rubber connector elbows for it and for the short line out of the purge solenoid. Both are severely dry rotted.

I need either the full harness/inspection port, or simply the two very specifically sized rubber vacuum fitting elbows that go into the manifold in front of the HVAC vacuum line and valve.

Any ideas? The part above does not look like it would work, but all the needed bits are there. The inspection port line is the top one, which goes to the hard line to the rear of the jeep, the lower line coils back to the manifold and has the 90º rubber elbow.

Anyone know from experience?

Again, this is a late TJ, so the LDP and all that crap live back in the passenger side rear corner of the tub by the tail light. It is not the system where all that lives under the hood. The parts/tubes/lines are not the same.

Not exactly. I used the OEM Mopar one, which looks a bit different. Went in without a hitch. I am concerned with the harness/inspection port and the nylon tubes which are formed to hard lines on my 2003. You seemingly cannot buy that. I can only find the version where the EVAP crap is all under the hood. So the nylon tubes are formed at different angles and lengths. I am not sure I can make the one linked to fit into my system, and I cannot find one I need. I think it is bonded to that one hard line that goes to the rear of the TJ, so that I would actually have to buy that hard line and what I need would be attached as an assembly.

You can get generic rubber elbows at just about any auto parts store. While the're not exact fit, they should work. They did for me.

You can cut the old parts off if necessary, and you can use a small hose clamp on the new one.
