Hey everyone, just got a preowned 2002 jeep earlier this month. Time to get my emissions checked and I am getting the 0442 error code.
I purchased a new EVAP Leak Detect Pump - no worries.
HOWEVER - while I was installing it, I accidentally dislodged one of the two hoses coming off of the purge valve. Where does the second hose connect to the intake manifold?
Any help is appreciated!

One hose to the intake manifold, I believe that runs through the evap solenoid to the canister down to the fuel lines and connects to the hard EVAP hose back.

Full and probably correct diagram in the factory service manual available for download in the resources section.

Thanks Mac, I appreciate it.
The issue I am running into on the schematics - none of them show the hoses (at least on the evap part of the manual).
So, I don't know where on the intake manifold to connect the extra hose.

if anyone has a similar jeep (02 CJ V6) - I would be very interested in a picture of where that final hose goes. (Specifically, the hose/solenoid that splits off near the charcoal filter, not the two thick hoses that go to the pump - these are the thin little ones)

I will post more pictures in the morning of what I am dealing with.

It's a pre bent/shaped hose, correct?

Can't you just connect one end and follow it to the general area at the other end where it connects, and look for it's pairing?
 
morning folks - I was able to get some pictures.
CJ with a TJ asked the right question, it is bent : but there is no obvious receiver or connection point for the end.

The first picture: It comes from the second hose off the canister.
The second picture - it naturally splits, with both ends going near the charcoal bit, just under the green part.
The third picture - you can see the natural curve to it.
The fourth picture - overhead shot, with me confused as to where it goes.

any help is appreciated.

I also included the 3 schematics that looked closest per the maintenance log.

The only one that looks like it shows a line is the first schematic - which shows EVAP line connecting to the fuel canister.

Thanks,
Ben

Thanks everyone! I was able to get it. There was a black rubber receiver off the silver intake manifold at an angle.

I still have to trip the Check Engine light, but I at least have completed my attempt at a fix.
