Where is the fuel filter located on a 1990 cutlass supreme sl?

On a 1990 Oldsmobile Cutlass Supreme SL, the fuel filter is typically located on the frame rail, near the fuel tank. However, the exact location can vary slightly depending on the engine (2.8L V6, 3.1L V6, or 3.3L V6 were common).

To be absolutely certain, you should:

* Consult your owner's manual: This is the best resource.

* Check a repair manual specific to your year and model: Chilton's or Haynes manuals are readily available. They'll often have diagrams showing the fuel filter's location.

* Look under the car: Start near the fuel tank and follow the fuel lines. The filter is usually in a somewhat accessible location along the fuel line.

Important Safety Note: Working with the fuel system involves gasoline, which is highly flammable. Take appropriate safety precautions, including working in a well-ventilated area, using safety glasses, and disconnecting the negative battery terminal before starting any fuel system work.
