Other Fuel System Tank Assembly problems of the 2001 GMC Sierra 1500

My anti lock keep kicking in, the panhead by gas tank is completely shot and there is a box by the gas tank for emissions and not able to get 1 and the frame in the front is shot also along with the body that's completely shot and the gas gauge keeps telling empty 1 time and then it goes to full to empty even after I fill it up. . .

I fully suggest that you do an investigation on GMC/chevy pick-up trucks. I, along with thousands of others are experiencing fuel gauge problems. The fuel gauges are going out very quickly. They constantly show that you either have a full or an empty tank when neither may be the case. You never know how much gas is in the tank. It also makes the low fuel light stay on constantly. There is currently no recall on this. I find this hard to believe considering the hundreds of thousands of these vehicles on the road. There have been recalls on far less serious issues than this. The quotes from GMC to correct it is up to $500. This matter needs urgent attention.
