A liquid tank (2) such as a liquid fuel tank, as well as a method of operating such a tank (2) and a structure (12) for implementation in such a tank, are disclosed. In at least one embodiment, the liquid tank (2) is a liquid fuel tank (2) that includes a housing (19) having an inner chamber capable of containing liquid fuel (16) as well as an air space (10) above an upper surface of the liquid fuel (6), and a floating member (12) included within the inner chamber (19), where the floating member (12) is configured to float proximate the upper surface (18) of the liquid fuel (9) when the liquid fuel (9) is present within the inner chamber. The floating member (11) includes at least one tapered surface, and the floating member covers a majority of the upper surface of the liquid fuel (9), whereby the liquid fuel (9) evaporates to a lesser degree than would occur if the floating member (12) was absent.
