Erratic Fuel Gauge Operation on Chevrolet Express 3500

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.

gas gauge gets crazy on a third tank of gas. have not corrected problem yet.
Our gas level indicator fluttlers fast, and rests at all different places. Our mechanic said it wouldn't be cost effective to fix it because, while the part is cheap, the cost in the labor involved would make it not worthwhile. Our solution: ALWAYS completely fill the tank. ALWAYS reset the trip milelage button at fill up. We know that generally we can drive about 400 mile hwy before fill up. Around town, I fill it at 300. Your mileage may vary. We know our city mpg is about 11-13mpg. On the road, 17 if we are lucky. :) Just never forget to reset that mile indicator and you'll be good to go!
