Outback 23RS two drain tube question

[jrhoads23]

So I have done a search and found various posts about the two clear plastic drain tubes underneath. My 23RS has the belly panels so I cant see what anything really goes to, so all i see are these two plastic drain tubes. I thought one would connect to the belly of the fresh water tank but that's not the case. I have removed both caps and hooked up a hose to my fresh water input (not the city water input). My thinking was it would immediately drain out of one of those tubes... it didn't. I had my hose hooked up 5 minutes and nothing came out of either tube. Just for fun I turned on my water pump and it started spitting out of one of them. So one of those tube must come AFTER the water pump.

What does the other clear tube connect to?

I would have to think somewhere there is a drain from the belly of the fresh water tank... where is that? There are no more tubes hanging down
