A portable, self-contained leak detection apparatus is provided which is particularly adapted for detecting a relatively small leak in a large fluid storage tank having a fill pipe. The apparatus comprises an air-tight chamber containing a liquid; a slope tube communicating between the liquid in the chamber and the atmosphere, wherein at least a portion of the slope tube extends along the outer surface of the chamber; a source of compressed gas in gaseous communication with the chamber; and a tube for communicating gas between the chamber and the fill pipe of the storage tank.
