Yeah, when I resealed my engine I looked for a hose kit but didn't find one either. It's really easy to get the hoses you need though. All you have to do is go to the local auto parts store and bring the hose you broke and they'll cut you whatever length you need. And this way it's cheaper and you don't have to wait for Subaru to ship them
.
ps: for some of the strangely formed hoses it might be a good idea to get the OEM so that everything fits correctly and you don't kink hoses
