The fuel filter on a 1993 Buick Roadmaster is located
on the frame rail, near the fuel tank, on the passenger side of the vehicle. It's usually fairly close to the rear of the vehicle. However, the exact location might vary slightly depending on whether it's a wagon or sedan.
Because it's under the car and potentially near the exhaust, always remember to take appropriate safety precautions when locating and servicing this component. Consult a repair manual specific to your 1993 Buick Roadmaster for the most accurate diagram and instructions.
