My '88 Blazer has a factory oil cooler which is leaking like mad. Does anyone know what kind of fittings are on the stock lines? If it's a flare type then I'm going to make up some new lines, but I need to know before I get the fittins and lines. If it's some kind of screwed up fitting like the fuel lines use then I'm probably going to run rubber FI fuel hose. I searched the forum already and everyone suggested having a hydraulic shop make up lines but there aren't many of those places around here.
