I do not know if you have anyone in your area that can make Hyd, hoses.
I would at least have them inspected.
If you are going to replace them I recommend you look up Bird's Radiator and Hydraulics Web site they are in Waxahachie, Tx. I was in their shop a several years ago on an unrelated issue with our old Motorhome. They appeared to have equipment to make or repair any tube or hose.
