E-Locker Question

[Four-CLT]

I'm in the process of cleaning up an e-locker. I noticed from looking at a picture of another locker that I am missing this black tube (circled in red). Does anyone know what this part is? I have a small metal tube that extends out maybe 5/16" from the motor, so it looks like I'm missing the black tube. Is it some type of breather?

There is a breather tube on the factory e-locker. I'd have to get under my truck to see if that is it. I routed mine up next to the rear diff breather extension.

Good deal. I did some further digging and found out that it is a breather for sure. Don't know why I couldn't seem to find any info last night.

Thanks for the quick reply.
