Abstract
A water separation unit includes a water separation portion. The water separation portion includes a component separation wall, a liquid chamber, and a gas chamber. The separation wall divides the water separation portion between the liquid chamber and the gas chamber. Liquid fuel is led to the liquid chamber. The separation wall includes a separation membrane, which water selectively permeates to be separated from liquid fuel in the liquid chamber. Water passing through the separation wall is temporarily stored in the gas chamber. A fuel supply apparatus supplies liquid fuel in a fuel tank to an internal-combustion engine. The apparatus includes the water separation unit. The water separation portion is disposed integrally in one of the fuel tank and a passage leading from a filler opening into the fuel tank, such that the liquid chamber is located above the gas chamber in a vertical direction of the water separation portion.
