The fuel can with water-separating member comprises a fuel can and a water-separating member. The fuel can may be a container for a liquid fuel. The water-separating member may be a non-planar, internal divider that creates a fuel chamber above the water-separating member and a water chamber below the water-separating member. Water may separate from the liquid fuel because the liquid fuel and the water are immiscible. The liquid fuel and the water may separate into a fuel layer on top and a water layer under the fuel layer. The water layer may lie entirely within the water chamber beneath the water-separating member such that the water is trapped behind the water-separating member when the fuel can is tilted to pour the liquid fuel.
