A fuel gauge that reads wrong, or fuel that does not move within the tank, can mean the transfer unit is failing, though other fuel-system parts can produce those symptoms too. Before replacing it, have a shop measure its resistance against the spec with the engine off, since the unit sits inside the fuel tank.
