After some terrific advice from "Bloders" I am ready to change my leaky power-steering pump. I do not want to damage the union so I assume I need a special tool of some kind. The HP union is sitting behind a metal pipe (Turbo?) and is awkward to get at. I have removed the air-filter & bracket, tensioning pulley, battery and tray in order to help access.
The union appears to be 18mm fitting into a 22mm. I feel that I need some sort of bent handled stilson on the 18mm.... any ideas?
I cannot see that it is possible to remove the pump complete with this hose attached because the other end looks to be inaccessable near the bulkhead behind the engine!
