power steering leak

[powerdog]

Can anybody point me somewhere to find this darn leak? I replaced the O ring thinking that's the typical place to leak. Put in a new one filled the reservoir and is still leaking. WHen I originally found it, the soft covering on one of the hoses was soaked and basically just falling off so I removed it. I suppose that was to protect the hose from heat or...anyway here are a few pics...seems most of the fluid is around the (tell me that's an injector) on the right front. But am getting little puddles at the base of the manifold. I just can't see where it's coming from...Should I replace the whole unit? Anything would be appreciated. 4 pics attached. Thanks
