Question about 2002 Oldsmobile Intrigue
Before you replace the sending unit try a bottle of Chevron's Techron Concentrate Plus to 12 gallons of gas in the tank. GM now recommends the use of a fuel additive (GM Fuel System Treatment Plus - part number 88861012) at each oil change which will help dissolve sulfur deposits on fuel tank sending units which causes the fuel gauge to go wacky. But Techron does the same thing as GM's additive and is widely available at auto stores and Walmart. See their site:

Classic symptom of a failing sending unit. It's inside the tank and on most cars it's replaceable separate from the fuel pump. I usually see them in the $45-75 range. Some cars have an access panel under the rear seat or in the trunk, where others require the fuel tank to be dropped - I'm not sure offhand which your car requires, however.
