The fuel filter on a 1992 Chevy Lumina is located
on the frame rail, near the fuel tank, usually on the passenger side. However, the exact position can vary slightly depending on the engine and specific trim level. It's generally within easy reach but may require getting under the car to access it.
Because of the slight variations, it's best to consult a repair manual specific to your 1992 Chevy Lumina's engine and model (e.g., a Haynes or Chilton manual). A visual inspection under the vehicle, referencing diagrams or photos from a repair manual, will give you the most accurate location.
