Today, U.S. Environmental Protection Agency (EPA) issued letters to portable fuel container (PFC or gas can) manufacturers encouraging them to add vents to gas cans to ensure safe and effective refueling. This announcement comes in response to years of complaints about slow, frustrating fuel flow from modern gas cans. With this reminder to manufacturers to incorporate self-closing vented designs, EPA wants to help make it easier and faster for Americans to refuel. (Source: EPA)
