I don't know of any rubber lines that will work with your YJ. If your local NAPA guys will let you, they will have a book that will have the specs on your existing lines and other vehicles. Look up what you have now and find some lines with the same fittings which are longer. I know that half-ton Chevy pickup lines will work on CJ's, so maybe that would be a place to start. Hopeflully someone else will know an exact fit for you, but if not you might try this.
