the head is -05 ORB, only reason I know that is from making the adapter to test pressure.
the lines are a common JIC, I think they are -06 but any hydraulic shop will have everything you need
probably need a-05 orb to -06 jic for the head side, and I would guess either a -06 orb to -06 jic or a -05 orb to -06 jic for the pump side
only reason I suspect the pump is -06orb is the magasine article showing the SRP1.1 details states they machine the pump from -06 to -08 orb fittings to get stronger threads
