The fuel gauge and fuel pump is one assembly in the fuel tank. You will need to drop the fuel tank. May be a loose connection or faulty sending unit

Water in fuel light just started to come on intermittently. Changed the fuel filters 3 weeks ago or 7500 miles back. Had never changed the filters on fuel or transmission since the first 80,000 miles....


The change in temperature from Las Vegas to Alaska could have resulted in condensation building up in your fuel tank. Also you could have gotten some diesel fuel contaminated with water. The transmission oil should be changed as per manufactures suggestion or at least every 50,00 miles especially if you are towing.

2000 buick century custom. fuel gauge fluctuates between empty and 1/2 when level falls below 1/2 tank. low fuel light works. problem sending unit (how hard to change), gauge, or other?


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 .

My 2000 gmc fuel gauge will sometimes go from full to empty causing the low fuel light to come on. Also it does not ever go below 1/2 tank mark.


needs the fuel pump assembly....gauge sender is incorporated in this module...pretty expensive but the only alternative is to fill it up and reset your trip odometer each time...you should be good for 250 miles or better before next fill up!! good luck!
