Fuel Hoses Lines/piping And Fittings problems of the 2007 GMC Envoy

About one month ago, after I filled the gas tank in my 2007 GMC Envoy, the gas meter would shift from f to e as I was driving and the light would come on. I would pull over to the side of the road, turn it off and back on. At that time, the meter would raise back up to the f but as I am driving again, it would drop back down and the empty indicator light would come on again. It has been doing this for a month now and I was even stuck on the side of the road once, njdot came to give me gas, thinking that was the problem, and the car still would not start. Had to get it towed to a gas station, where it then started and I was able to make it home. The car also hesitates (drags) when I'm trying to give it gas, as if it's going to cut off. I was told it was a clogged fuel line and will have it checked but this can cost me $600-800 that seems to be a problem with these trucks. I have read many stories from others who have the same vehicle.

Fule gage shows empty. Same also occured on my 2006 Envoy. Gm will not repair either Envoy unless I pay approx $600. I would like to see a recall and the parts used to last. Safty is also a concern as check light goes on and off and you have to estimate fule used. I see on line that this is a problem for gm. Has gm improved this fuel sender?.

Sending unit inside of gas tank: when full of gas, gauge says below empty & gas light comes on. When 7/8 full to almost empty gas gauge reads correct, when empty gas gauge reads 2nd to last line, car runs out of gas & no gas light comes on. When you are driving at 50 mph and run out you could crash. When car is parked for 4+min. Gauge goes below empty & fuel light comes on.
