Where did these come from?

In cleaning out the main power relay + Vanner compartment over the weekend, I found a handful of parts the previous owner of my coach deemed to be "extra". Anyone have any ideas where these could've come from? Looks like a mix of braided, and rigid tubing.  I suspect I'm not providing you all with enough information to get an accurate answer - but I figured I'd ask.

Since one of the hoses is clearly broken, I am guessing that it was replaced and, for some reason, not thrown away.
