Hello Everybody, I just joined to board. I have a 1978 Buick Park Avenue (Electra body) 350 V8 4 Barrel. Now I am restoring my car and I am having problems with vacuum system and connections. I appreciate if you can help me about finding vacuum diagram for this engine. Thank you very much
Not sure we can help unless a member happens to have a 1978 PA as you do. What I would do is get the 1978 Buick Chassis Manual. That would answer every question you might have. Fortunately, they are available on E Bay at very reasonable prices. http://www.ebay.com/itm/1978-Buick-...ash=item1ebfe13836:g:DBkAAOSwCGVX3gZw&vxp=mtr http://www.ebay.com/itm/1978-Buick-...ash=item1a235dfb09:g:8agAAOSwX~dWlwMV&vxp=mtr http://www.ebay.com/itm/Factory-OEM...ash=item5b3126e3c6:g:glIAAOSwhQ5XQRZA&vxp=mtr
