Question about 1987 Buick Regal
Not sure of your engien size as you didn't say so I went with the most common enegine the 3.8 liter. Again I wasn't sure of what vacuum diagram you needed as the is vacuum for emissions, air conditioning and cruise control. the picture above is for emissions for the 3.8 liter engine. Hope this was what you were needing but if you have a different engine (305 or the 3.8 turbo) you can reply back here with what diagram you needed or the correct engine. Hope this helps...
