The fuel gauge is reading more fuel than is actually in the tank. And by the time my fuel light comes on I have about 2-5 miles before the "ECM B" 20 amp fuse pops, killing power to my fuel pump and bringing the truck to a stop. This has happened twice so far. Now I just fill the truck up once it reaches about 250 miles on my trip to keep this from happening again. My friend told me that the fuel pump and the fuel quantity system are the same part on this truck and that it needed to be replaced. I think he called it the "Sending Unit"? Does my friend know what he's talking about or do I need to look into something else? Any help would be greatly appreciated.

I dont know if we are having the same problem but when ever i fill up my 99 silverado the gas guage goes back in for from empty to full for the first 30 or so miles. Then it is normal the rest of the tank. Does anyone have any ideas whats wrong
