The fuel filter on a 1990 Chevy Suburban is located
on the frame rail, near the fuel tank, typically on the passenger side. However, the exact position can vary slightly depending on the engine and specific options of your Suburban. You'll likely find it in the area where the fuel lines run from the tank toward the engine.
It's recommended to consult a repair manual specific to your 1990 Chevy Suburban's year, model, and engine size for the precise location. A diagram in the manual will show you exactly where it is.
