Power steering Hose connection in frame question

[porsche996]

The connection for the power steering hose that's in the sub-frame... Does anybody know what size wrenches to use to tighten it? Basically, all my tools are in a storage unit about a half-hour away from the house, and I so I have to be selective as to which ones to grab to use for any given job.

If someone could tell me what size wrenches I'd need, it'll be quicker for me to just go to the store and buy a couple than to make 2 hours (down and back twice) to my storage unit. Odds are, with gas prices these days, it's probably cheaper to buy new tools, too!!

Thanks!
