What You'll Learn
The fuel filter is located in the carburetor
The fuel filter on a 1986 Buick Century is located in the carburetor. To access the fuel filter, follow the metal fuel line that goes into the carburetor and remove that line. Then, remove the large 1-inch filter housing that the fuel line went into.
Before removing the fuel filter, it is important to relieve the fuel system pressure. To do this, first disconnect the negative battery cable and remove the gas cap. Then, look under the hood on the fuel rail for a Schrader valve (similar to the type found on a bicycle tire). Place a rag under the valve, remove the cap, and press the valve with a plastic pen to release the pressure in the line.
Once the pressure is relieved, you can go underneath the car to remove the filter. Be careful of any fuel remaining in the line and ensure there is no smoking or sparking during this procedure. There should be one bolt securing the filter to the frame. When installing the new filter, note the arrow on it and install it in the correct direction. Finally, replace the cap on the Schrader valve and reconnect the battery cable.
