Fuel gauge not working

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your K1500. It sounds like there could be a mismatch between your fuel gauge reading and the actual fuel level in the tank. This often happens if there's an issue with the sending unit (inside the fuel tank) or if the wiring has a poor connection. Since the gauge moves but isn't reading accurately, you might want to check the ground connections and wiring to ensure they're intact and corrosion-free. The sending unit on these models is part of the fuel pump assembly, so if the replacement pump was low-quality or misaligned, it might contribute to the inaccurate readings. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered.
