SOURCE: how do I change the fuel filter in a 1999 Buick Century Custom?

Philly, the fuel filter is attached to the frame in front of the gas tank, under the driver side of the car. You must relieve the pressure in the fuel line before you start, and it is also recommended that you disconnect the neg. battery cable. After disconnecting the neg. cable, remove the gas cap. Next, look under the hood on the fuel rail for a shrader valve (like the type on a bicycle tire). Place a rag under the valve, remove the cap, and press the valve in with a plastic pen to relieve the pressure in the line. You can now go under the car to remove the filter. You can disconnect the fuel lines easily with an inexpensive plastic disk made for this purpose (only a few $ for several sizes at a parts store). Be careful of fuel in the line that will drain out, no smoking or sparks during this procedure. Should be 1 bolt securing filter to frame. Note arrow on new filter, and install in the correct direction. Replace cap on shrader valve, put gas cap back on, reconnect battery cable. The low coolant light is probably a faulty sensor signaling that it's low, when it's actually ok. Look for wires coming from the reservoir bottle, you should be able to find the sensor at the end of the wires to replace it. If you change the fuel filter in a garage, leave the door open for air circulation, gas fumes can explode easily, having the door open will help dissipate the fumes.

Hello, the crank position sensor or (CPS) censor is located directly behind the harmonic balancer (or fly wheel at the very bottom). The sensor is located on the right side of the harmonic balancer when facing the front of the motor. You must remove the harmonic balancer to replace the sensor. You must also re-align the sensor with 30 thousands of an inch tolorence, or your car may idle rough or may not start. I own a 1990 Buick Century and just replaced my CPS sensor last month. There is a trick I learned to reinstalling the new sensor. Let me know if you need that information.
