Erratic Fuel Gauge Operation on Chevrolet Avalanche 1500

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 Chevrolet Avalanche 1500 162,000 mi,
my gage on dash does not read at all it tells me i am low on fuel when I just filled it up it seems stuck
2004 Chevrolet Avalanche 1500 150,000 mi,
Gas gauge shows various levels of gas each time the key is turned on. Gauge moves slowly up or down when driving stopping at times. Don't know if problem is with gauge or sensor.?
When I fill my tank up for the first 18 miles my gas gauge reads as empty with the gas light on. Once it has surpassed the 18 miles it reads normal.

At approximately 12 gallons remaining in the tank, I begin to get "low Fuel" warnings and actual fuel gauge will appear to register below "E", then will ease back up to between 1/2 and 1/4 tank within a few minutes.
Fuel gage reader will move up like a half a tank sometimes when I push the gas but then when I slow down the reading will drop and show me on E when I have a quarter tank of gas in it. Happens off and on. I haven't got it fixed.
2004 Chevrolet Avalanche 1500 171,760 mi,
I put $50 dollars worth of gas in my tank, around 12 gallons, and when I left the gas station I had a nearly half a tank. (I believe it holds 30 gallons including the reserve.) Not even 24 hours later and not that much driving shows me on my reserve tank again! WTF?!?!?!
2005 Chevrolet Avalanche 1500 191,640 mi,
Filled up my tank with 20+ gallons and fuel gauge is showing 3/4 full. I have a 2005 Avalanche 1500
At around 70,000 miles I ran out of gas on the freeway as the fuel gauge registered 1/4 tank.
