Changing Fuel Filter: 2002 Buick Century Guide

If you're looking to change the fuel filter on a 2002 Buick Century, you'll need to locate it first. The fuel filter is always found between the fuel tank and the engine. For most vehicles, the fuel filter is located inside the top of the fuel tank, where it connects with the fuel line. However, in some cars, it might be elsewhere along the fuel line. In the case of the 2002 Buick Century, the fuel filter is under the vehicle, on the driver's side, below the seating area, in front of the fuel tank, mounted on the frame rail in the fuel line.

Now that you've located the fuel filter, it's important to relieve the pressure in the fuel line before starting. It is also recommended that you disconnect the negative battery cable. After disconnecting the negative cable, remove the gas cap. Next, look under the hood on the fuel rail for a Schrader valve (similar to the type 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. You can now go under the car to remove the filter. Be cautious as fuel may drain out, so no smoking or sparks. You will need pliers and two wrenches to undo the filter. Note the arrow on the new filter and install it in the correct direction. Finally, replace the cap on the Schrader valve, put the gas cap back on, and reconnect the battery cable.

Then, replace the cap on the Schrader valve and put the gas cap back on.

Finally, reconnect the negative battery cable. Ensure the gas cap is on before reconnecting the battery.

It is recommended that you leave the garage door open for good air circulation when changing the fuel filter, as gas fumes can easily explode.
