Price would depend on where you live and where the part is purchased. The tank would need to be removed to replace the sending unit and the pump is usually included.
Cost of parts could be over $400 plus labor.

SOURCE: Where is the fuel filter located for Buick Century 2001

The fuel filter is located underneath the car in front of the gas tank.
You have release the fuel pressure. Remove the fuel filler cap, locate the fuel test port on the fuel rail on the passenger side on the end of the right real fuel rail for a 3.1L engine.
3.8L engine yhr test port is located at the pressure regulator under the trim cover.

SOURCE: 2000 buick century custom. fuel gauge fluctuates

The sender unit has a fine resistance wire with a slider to read the level, the slider or wires are worn and making intermittent contact, the low fuel light is a seperate switch so it will still work.access to the sender is usually under the rear seat cushon, under the soundproofing and a cover, have a look and describe what you have .

2001 Buick Century, fuel gauge shows correct when I first start the car, and the "low fuel" light comes on at the correct time, but otherwise, always shows full. Can't be the sending unit, since it is...


Only four tings it can be. The sending unit, the gauge, wiring or the PCM. So you are saying that you keep your car full all the time? Replace the sending unit. 99% of the time it is the sending unit. .9% of it could be a gauge. .1% is the PCM.

How to replace the fuel sensor on a 2001 buick century.


If you mean the fuel level sender for the gauge it is part of the fuel pump module inside of the fuel tank. If you mean the fuel tank pressure sensor for the EVAP emission system it is located on top of the fuel pump module on the outside/top of the tank. If you have an erratic fuel gauge then the sender is most likely at fault. Some are serviced seperately but some are sold only as part of the pump. If you have to remove the tank and pump to replace the sender and have close to 100k on the odometer then I would STRONGLY suggest replacing the fuel pump at that time.
