Depends on your pocketbook and how much time you want to spend on replacing lines, myself , I purchased a coil of 1/4" o.d. and a coil of 3/16" o.d. both came with fittings and a double flaring tool kit is inexpensive and you don't have to piece it together and be concerned with multiple connections leaking. Not sure about your truck but I dropped fuel tank on mine to replace line from front to rear. Spent less than $50 on material, already had tools, just takes time and patience and re'ck your connections a few times hot and cold outside temperature will affect seating of connections. You can get lines from just about any parts store but price is more and you have a choice of brake line kits with galvanized, copper coated or stainless which can be more money. Just depends on what you want to do, your mechanical experience , tools and time. Hope this helps and good luck
