What is this hose used for?
I'm curious what this hose is used for, and what is put through it... It connects to the plastic piece (marked in green), and it's in a bit of a tight spot further down. I was wondering if I should re-route it, so it's not being squeezed at all (it's only barely being squeezed right now, but I want to make sure).
So, what is it for, and what is put through it?
