Abstract
A system, method, and article of manufacture for reducing the rate of fuel vapor formation within a fuel storage tank include a plurality of discrete independent floating particles or elements to reduce exposed evaporative surface area of fuel in the fuel storage tank while conforming to a changing fuel tank cross-section as fuel level changes. The elements or particles may have a self-tessellating geometry to facilitate formation of a single or multi-layer barrier or cover and be made or coated with a material that resists fuel wetting and degradation, such as a highly fluorinated polymer including polytetrafluoroethylene.
