A tank level indicator having a mounting sleeve and a floating indicator rod slidably mounted in the sleeve. The sleeve has an inner wall from which projects inwardly a series of circumferentially spaced guide pads with gaps therebetween. The pads guide and space the indicator rod with respect to the inner wall. The remainder of the sleeve interior is free of such pads to leave a substantial clearance space between the inner wall of the sleeve and the indicator rod.
