This kit replaces all the vacuum lines under the hood. It also includes an extra twelve feet of hose to allow you to replace your radiator overflow and windshield washer hoses if desired. This is a pre-cut kit and it includes the needed vacuum "T"s. It's very important to have leak free hoses and connections on the supercharged 3.8. Now that they are old, the factory hoses often leak under boost causing incorrect pressure signals to reach kit the map sensor, fuel pressure regulator, and the supercharger's bypass solenoid and bypass actuator. If your supercharged Buick is a little low on power, or has higher than normal fuel consumption or emissions this kit will probably help.
