Abstract
A fill head assembly for a fuel storage system includes a check valve disposed within a central region of the fill head assembly. The check valve includes a membrane covering a vent outlet of the fill head assembly. The check valve prevents liquid flow from the central region into the vent outlet, while simultaneously allowing vapor flow from the central region into the vent outlet. The membrane includes a micro-porous material that is liquid impermeable, thereby preventing liquid flow through the membrane, and is vapor permeable, thereby allowing vapor flow through the membrane.
