How often have you spilled gasoline while filling a lawn mover, chain saw, or other small fuel tank? The No-spill gas can works similar to a laboratory squeeze bottle to reduce spills and the amount of volatile hydrocarbons released into the atmosphere.
Simply lay the gas can on its side with the pump facing up, and apply foot pressure. As the pressure in the can increases, gasoline flows through a permanently attached hose. When you stop applying foot pressure, the gas flow stops.
