2011-2014 V8 - serious issue - Coolant Pipe Glue

My 2011 Cayenne Turbo had a coolant leak. The leak came from the rear of the engine, a coolant pipe glue failed and popped-out, it let me stranded.
My indy shop took care of the repair, and went the extra mile to install a new water pump, new thermostat, new thermostat housing and a couple of hoses that tend to fail with age/miles. My CTT has 80k miles.

I completed the install at the thermostat housing, she is running good and back on the road with no leaks
I also did end up finding that connector clip, it was on the garage floor lol
Does anyone have a upgraded part number or part list to replace the rear leak location? Or is the only solution fabricating the connector? Attached is a picture of where I believe the rear leaks from, can someone please confirm.

My coolant pipe fix seems to be working. My observation was the housing surface was too smooth of a finish for the glue to adhere, it was really stuck to the pipes.
OEM glue did not stick to machined housing
Glue stuck to pipes, needed to file it off
Cleaned, surface roughed and ready for epoxy
Done!

The fit was quite loose, so I don't see much of a problem with the JB.... I would spread a thin coat on both surfaces with finger (wearing a glove) to insure full coverage and not getting too much excess inside when pipe installed. Twist pipe when installed to ensure complete contact and coverage. I used the radiator hoses to hold the pipes in proper position while epoxy set.

The epoxy I used was the epoxy I use for replacing/installing golf shafts in the club heads. It was a bit more liquid than I would have preferred, however it seems to have worked, I have about 3K miles on it and no problems.

Thought I'd update the thread a bit. I had my thermostat housing replaced by the dealer. Cost was actually reasonable IMHO.
Here is why:
Surprisingly - the pipe doesn't feel loose on the bench, but on the car, engine hot, I could wiggle that pipe and it moved.

What's reasonable in this case? For a water pump plus tstat service which I'm gonna be generous and assume includes this repair (I didn't know about it at the time) I was quoted roughly $2500.00

The water pump must be removed to replace this part - so - that would be the time to replace it if you haven't already (I did - mine was relatively new..) - my cost was less than half what you were quoted, although they did say that they'd underestimated the labor on the job, my WAG was it would have been about $1800 if they had estimated the labor correctly. If you also did the thermostat and water pump at the same time I could see the price going around where you were quoted.
