2003 Buick Park Avenue Question: In-Line Fuel Filter
Answer #1Jim Taddei February 24, 2011, 16:58Master
The fuel filter on your 2003 Buick Park Avenue is located at the left rear, inboard of the subframe. Their may be quick connect and/or threaded fitting on the fuel lines. You may need a special tool depending on the type of quick connect fitting used - GM uses several.
