Well im almost done rebuilding my 92 RS, I have most of the engine back together. Just got the heads back on, the intake, and manifolds. Soon ive gotta adjust the valves and ill be back in buisness. Needless to say my vacum lines are a mess, they are all dry rotted and half are split or just not conected to anything. Does anyone know if I were to replace ALL of the vacum lines what diameters I would need and what approxment lenght of each diameter. From what I saw there are a couple different sizes in there. Any help would be very much appreciated
