I'm currently rebuilding / modifying a front end loader on my tractor, I'll be getting a mobile hydraulic hose guy to come and fit it out with hoses and couplings, I might see if he can do the oil hoses on the Jag at the same time. Makes sense as he'll be here with all the equipment and know-how. My experience with hydraulics is very little and mostly in replacing like with like, so I'm not conversant with the different types or their advantages / disadvantages.
