It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.Google+

Gas gauge stopped reading correctly. Diagnosed by dealer as the gas tank module. Buick wants $700 to install new one, parts and labor. What a ripoff. We keep track of mileage but my old Toyotas never had a failure like this in only 10 years!

mechanic said it would be $500 to fix so i didn't. it became erratic at less than half a tank.
it doesn't register properly. I just keep track of the mileage.

Erratic Fuel Gauge Operation due to faulty plastic on the part. Opted to NOT replace, just watch the mileage on the car and fill tank every 100 miles of in town driving.
