Problem Description and Possible Solution

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.

Started acting erratic at 80K miles. At 130K miles now. I knew of this issue when I had a 00 Pontiac Bonneville. Its an issue of cost cutting on GM design and the floater failing. Does Not cause any harm and I've learned my car. Also Now I go by the millage to when I need to fill up.
