Q: Where is the fuel filter located on Buick Century and Regal?
A: The fuel filter is behind the fuel inlet on the carburetor. Next, disconnect the fuel line from the filter nut, remove the nut, and the filter and spring. For fuel-injected engines, the filters are on the frame rails or rear cross member. Then, depressurize the fuel system, disconnect the battery cable, and remove the filter and O-rings.
