I recently had a hydraulic oil leak in my leveling system. I had to have a short hydraulic line made. We removed the old one and took it to the shop. The guys made a new line with the identical end fittings... and we simply put the new one on, refilled the tank with oil, and off we went... $225 poorer, but it took only 1 1/2 hours, and half of that time was getting the new, little, hydraulic line made.
Where's Gerald? He would know how to fix this. Be patient. Gerald will come along soon.
