[Cholo Mike]

Hello my name is Mike! In the morning when i start my truck i hear the thump like something is under the 4x4 stick in the center or something. but for last 2 years been trying to figure out my fuel gauge flicker? I don't seem to find anything on answers to this has anyone figured out what there's was? Can anyone be more specific or help me out on where to start besides dropping the gas tank! I hope it doesn't come to this!
