Always be sure to use the correct replacement bulb for the best life expectancy. The new bulb recommendation for 1999-2003 models is #4114K (trade number).
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.
