best way to find a leak is to scan or spray carb cleaner on the vac lines with the car running and listen for idle change. I think an engine diagram would be the easiest way to find all the lines for you, but they are for the most part easy to spot, and if they are hardended or you see visual cracks I would say just replace them. Hope this helps
