* Frame Rail: Most likely, it's located on the frame rail, somewhere near the fuel tank, usually on the passenger side. It's often a cylindrical canister and may be hard to see without getting under the vehicle.
* Engine Compartment (Less Likely): While less common on this year, some configurations *might* have it in the engine compartment, but this is less probable.
To find it definitively:
1. Consult your owner's manual: This is the best resource. It will show a diagram of your specific Suburban's fuel system.
2. Use a repair manual: A Haynes or Chilton manual for your specific year and engine will have detailed diagrams and instructions.
3. Online resources: Search for "1997 GMC Suburban fuel filter location [your engine size]" on YouTube or a car repair forum. You'll likely find videos or pictures showing its precise location.
Remember safety first! Always disconnect the negative battery terminal before working near the fuel system to prevent sparks. Fuel is flammable and working on it requires care.
