Well I have a hole in one of my lippert leveling jack hoses. So all the hoses have the plastic jacket falling off them so I though maybe I would do the back 4 lines now and the front 4 later. Well may...
I have replaced all the orange line, all of it was leaking or would be shortly. As others have said go to NAPA and have replacements made. I think it cost me about 300.00 for all of them. Take a line in with you so they can match the fitting and either bring the lines in or measure them. I took them all in and had them make them a foot longer.
