You will need to fill the chamber somehow. To do this you drill a hole in the endcap and glue in the valve. Mark the center of the endcap and clamp it in a vice. Get your drill. A standard schrader valve is around 5/16", but the hole will need to be a little larger if you're using a snap in valve. Save yourself some time and make sure you use a power drill and vice.
