Power Steering leak from failed union

[FIFTY]

Hello good people

I have a very annoying power steering leak. I won't go into the history as it is very frustrating (repaired twice but continues to leak by a garage I once used but no longer)... what I need from the collective is some help deciphering the part numbers for some new unions

The leak is from the front right hand corner of the car (UK off side/drivers side) where there are two PS unions below the engine oil feed line, above the thermostat and radiator hose. It is the union that is further down that has failed which is quite difficult to reach. It does look a bit like it has been cross threaded also.

I'm struggling to figure out which one it is as the diagram shows the LHD configuration: https://www.eurospares.co.uk/parts/maserati/4200-coupe/suspension-steering/steering-box-20157

I replaced the pipes on mine, they should be one piece, parts 6 & 7 in the eurospares link.
Has a repair section been fitted on the pressure pipe? as my pipes had leaked on the rigid part of the pipe at the front of the engine where the bracket had rubbed. A repair section of pipe could have been fitted in my case but opted for new

No repair it is stock. Guess the union and hard pipe is needed to bring the hoses around the radius on the corner of the engine

I'm going to get it booked in and replaced. I don't own the spanners needed to get the oil pipe off or the ones for the unions and I don't really fancy buying them as they won't get used a just clutter up my toolbox
