A filler neck insert to be removably attached to a capless fuel tank filler neck of a motor vehicle so that a source of pressure or a source of vacuum can be coupled to the fuel tank in order to test the fuel tank for leaks. The filler neck insert includes a hollow tubular body to be received through the open fuel-mouth and suspended within the throat of the fuel tank filler neck and a base extending across the tubular body. An adapter which is connected to the filler neck insert has an outer rim mated in surrounding sealing engagement with the base of the insert and an inlet tube connected to the source of pressure or vacuum. Accordingly, a flow path is established from the pressure or vacuum source to the fuel tank by way of the adapter, the insert and the filler neck.
