I have a buick lesabre costom 1987 3.8 .I had the engine rebuilt,now i need to know where the vacuum hoses go so i can finish this project?
I need to know where the vacuum lines on the throttle body side,from the brake booster
small vacuum line, and the plentium beside the thottle down to the modulater?
Look under the hood for the vehicle's emission control label. It'll have a vacuum hose routing diagram. If it's gone then visit your local Buick Dealer. They may be able to get it from a factory shop manual. If all else fails, try ebay for a factory shop manual. HTH -Jim
