The fuel filter on your 1991 Buick Park Avenue should be located on the underside of the car, possibly near the fuel tank. You may need to follow the fuel lines from the fuel tank to see exactly where the filter is located.

The filter is located under the car on passenger side closer to the front wheel all book say other places but that is where it is after looking all over the underside
follow the fuel lines along the bottom of the car to the passenger side firewall where you will see it.
