Erratic Fuel Gauge Operation on GMC Yukon Denali

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.

2003 GMC Yukon Denali 125,000 mi,
Fuel gauge reads about 1/8-1/4 tank lower than actual level. Low fuel warning comes in at expected gauge reading but again the gauge reads incorrectly low. I know the gauge reads low due to the amount of fuel I can add now at a particular fuel level reading compared to how it once was.
