If you take out the engine pump and join the hoses, nothing will happen to the direction, but it will be very hard. If abuse of the direction thus, eg parking to park) you will load the orbitrol (distributor valve).
In addition, have you thought about what to do with the belt? The Kangoo Diesel has a multiservice Correa, the steering pump, the alternator, and the AA compressor van with the same belt, and it is going to be long.
I don't know the pressure hose, but in a hydraulic house where they make hose, taking the pump or the threaded corner they tell you quickly and they even make the hose if you need it.
Greetings I hope I have helped you.
PS There are hydraulic exchange or scrapping pumps that can come well for you.
