2004 Buick Rainier Question: replace fuel filter
The fuel filter on your 2004 Buick Rainier should be located on the side of the fuel tank. If equipped, a splash shield may need to be removed.

Unless a special release tool is required, only ordinary hand tools should be required to replace your fuel filter. If you have trouble with the quick release and can some how describe it, I can try and talk you through it. - Jim Taddei
