2006 Buick Lucerne Question: fuel filter
Answer #1Russ March 25, 2009, 20:34Master
I cannot find mention of a fuel filter for your Lucerne anywhere! I would suspect it is part of the fuel pump module inside the fuel tank. Most new GM cars and trucks are going that route - don't ask me why. The filter would only be changed when the fuel pump fails, on its own or due to fuel contamination. The fuel pump module is replaces as a unit.
