On a 1995 Chevrolet Silverado with a 5.7L V8, the fuel filter is typically located
on the frame rail, near the fuel tank, on the driver's side of the vehicle. However, the exact location can vary slightly depending on specific options and trim level. It's usually a cylindrical canister, and might be somewhat hidden. You'll likely need to get under the truck to find it.
It's highly recommended to consult a repair manual specific to your year and model Silverado for a precise diagram and location. A Haynes or Chilton manual would be helpful.
