The hoses are the easy part. They should be AC type hose, or as mentioned above, teflon lined hoses. Hoses for hydraulic oils are different. The fittings at the ends of the hoses are the hard part: you will need to reuse them.

The fittings are pretty simple. They have a barbed end that gets shoved inside the hose, and then a crimp collar goes over the joint and gets crushed tight. You can cut off your old crush collars and remove the hose from your barbed fitting ends and they're ready to reuse. Now with those in hand, any hydraulic repair shop can assemble the new hoses to your fittings with new crimp collars.

The thing that makes it tough, is that the crimping process is tight enough that you can't rotate the fittings inside the end of the hose, and the hose itself won't twist....so you need to have the fittings pointing in the right direction before they crimp them down.
