Mounted on the loader, you will have long runs of hoses 12' t
o 15' long. I don't know this for sure, but probably 1/2" hose would supply better flow than 3/8" hose. I really have no experience with with how the QA plate augers are set up, but it's worth checking/asking to be sure you get the correct setup. One thing I know for sure. !/2" hoses are far harder to route and deal with than 3/8" hoses. However, if they make a big difference, you have to consider them. Your rear remotes on the tractor will be 1/2" quick-connects.
Its designed to bolt to the bucket but I'd rather have a dedicated QA plate for it.
I haven't priced the hoses yet. I think landpride offers a hose kit too.
