Within the tubular spout is a dripless valve that moves to an open position allowing for the flow of fuel out the spout and to a closed position shutting off the flow of fuel out of the spout. According to the present invention at least a portion of the dripless valve surface has a surface energy less than the surface tension of the fuel being dispensed.
