I replaced the brake and fuel lines on my '90 LeSabre this past fall. One thing I can say is that it is time consuming and at times challenging. I tried all my local GM dealers looking for that repair kit that contains the lines that yogi mentions in their post. None of them knew what I was talking about, and the same went for the dealers who sell online that I am in contact with. I ended up buying the fuel lines at the dealer for just over $50( parts guy gave me discount because I used to work with him ,otherwise it would have cost close to $70.) That covered from the front of the vehicle to the fuel filter. I ended up replacing the tank, and sending unit, and the lines that went from the sending unit to the filter. All the brake line was purchased at Autozone along with a flare tool kit ($9) which we found out was a very important tool to have. This allowed us to custom make the lines that we would have had to locate through the dealer,(which most dealers no longer carry as the vehicle is too old.) Some of the OEM lines from the car had special fittings on the end. These generally are not available at the auto store. Cut the old line and save the fitting,then put that fitting on the new line then use the flare tool to duplicate the particular flare. Keep in mind that GM used different size flares on these lines, and do not discard the old lines until you have duplicated the same flare on the new line and installed it. Plus having the old lines around makes it much easier to duplicate the bends and turns in the new lines. I can't remember how much the brake lines cost me as I ended up going to multiple stores for all my lines that I needed, but I believe it was under $100. Cost wise, I would think the steel lines would be less expensive, besides I'm not sure if your state allows rubber to be used for brake lines if they have safety inspections. My state doesn't allow compression fittings to be used, rather they want the kind of fittings that are found on the steel lines. Make sure you carefully look at how the lines were routed and where each line goes to when you reinstall it. The LeSabre's brake system was quite different than some of the other brake systems I had worked on previously, but it is still fairly easy to understand and navigate.
