Power Steering Pump Bad Leak

This week i noticed a leak in my power steering pump. It was dripping in my parking spot and the engine bay and right inner fender are all fluid washed. First o thought that was the o'ring in the reservoir, replaced and it gets worst. Once i have re-used the copper washers in the pressure line, i'm pointing to this. Does anyone know the size of this copper washers? Its pretty messy to work with the ps pump, i want to have the new washers in hand before start to disassemble.

 

Have you ruled out a leaking hi-pressure hose?

 

Yes, i can feel the leaking spot under the pump body, right in the hi-pressure connection bolt.
