power booster/assist for brakes

Got an 02 f250 superduty, its has the power booster or assit\ unit for the brakes thats fed from the powersteeing pump. Theres two feed lines from the looks of it, one on the drivers side and one on the pass side of the unit, both lines are on top. The one on the pass side is pissin fluid out between the line itself and the fitting. I popped the line off and theres a flare and an o-ring at the end of the line. O-ring looked a little crappy so I put a new one on, exact same size, and it still leaked. The end of the line looked good so the only other thing I can think of is maybe theres something screwed up with the booster unit and its not allowing the fluid to flow properly and its being forced past the o-ring and then leaks out the fitting. Any help on this would be great, really cant afford to be taking it to the shop and I just can't understand why its leaking. Brakes and steering were fine then I heard my ps pump whining and found that it was low on fluid and also found the leak.

The line that leaks is the feed to the brake booster, the other line which i thought was also a feed to it is actually the feed to the steering gear box. Then it returns to the ps pump.
