The fuel filter on a 1992 Buick Skylark is located
in the fuel line, typically near the fuel tank, under the vehicle. It's not easily accessible and you'll likely need to get under the car to find it. There's no single easily visible spot; its precise location might vary slightly depending on the engine and trim level.
Because it's under the car, you should consult a repair manual specific to your 1992 Buick Skylark for the exact location and proper replacement procedure. A diagram would be extremely helpful. These manuals are often available online or at auto parts stores.
