Where are the vacuum lines located
Vacuum lines on 1994 Pontiac Grand Prix
There is a main vacuum hose that goes from the intake manifold to the brake servo unit, there is always a vacuum hose that goes to the fuel pressure regulator, and there is a vacuum hose that goes to the fuel tank evaporate emissions purge valve. There should be a label under the hood of your cars with emission equipment details and a vacuum hose routing for your car's engine. If not look at Autozones website once you register they give you access to workshop manuals for many popular cars fro free.
