Can anyone identify this hose?

[IceBlade]

I know where it goes but I need to know the part #. It's an elbow hose that connects to something right next to where the oil dipstick goes into the oil pan. It's the smaller coolant hose 7/8" in diameter and 5" long which attaches to a metal tube from above that runs up and under the intake manifold.

I just found this how-to and I believe it's the one on the bottom right that says HG11101? I can't seem to find that part online. Can anyone help? I don't know where to look for this. I went to a couple of places in walking distance but it seems they're all useless so I may just have to order the part from the Subaru dealership. I provided a picture below as well.
