Sock inlet check valve for fuel tank

摘要

Reducing fuel vapor within a vehicle fuel tank is accomplished by employing a flexible fuel sock attached to spud near the top surface of the fuel tank. The fuel sock resides within the fuel tank and retains liquid fuel during tank refueling so that the fuel is confined within the fuel sock until the fuel reaches the bottom of the fuel tank or the current level of fuel within the tank. The fuel conduit may be flexible and buoyant to accommodate any level of fuel in the tank and reduction of fuel refueling vapors. A check valve may be situated within the spud.
