How do you replace the fuel filter located on a 1992 Oldsmobile Cutlass Ciera?

Filter is located behind fuel tank, some were a quick connect style and most invoved a fitting on each end> look carefully at new filter. Sometimes the fittings rust to the line, use a penetrant. If you can loosen and disconnect at least one fitting, sometimes you can spin off the filter without freeing up the fitting on the other side>
