Where is the fuel filter on a 2006 Chevy truck?

The location of the fuel filter on a 2006 Chevy truck depends on the engine. There's no single answer. To find it, you'll need to consult your owner's manual or a repair manual specific to your truck's engine (e.g., 4.3L, 4.8L, 5.3L, 6.0L, etc.).

Generally, on many GM trucks, the fuel filter is located somewhere along the frame rail, often near the fuel tank, but sometimes closer to the engine. It's usually a cylindrical canister. Looking under the truck near the fuel tank is a good starting point, but checking your manual is absolutely necessary to avoid wasting time and effort.
