2011-13 Qx56 cooling system discontinued part help?

[Eli-2011Qx56]

2011 qx56
Does anyone know of a source for part:
14075-1LA0A

I have a slow leak. The infinity dealer can not locate it.
This part is discontinued.
I have tried every place I can think of.
Nissan parts.com
Infinitypartsdeal.com
Yoshiparts.com
Qualityautoparts.com

If anyone has a source or workaround, I would greatly appreciate it.

Is the pipe cracked? Might have to go to a junkyard or repair the one you have.
