I'd go to walmart and buy a cheap double action pump, they usually come with several nozzles to fit different things. One will slide on the end of that I bet. Or a cheap 12v low pressure/high volume pump for inflatables, it won't take much to inflate that though. It almost just looks like a mouth valve to me....you only have to do it once! lol Or cut it off and buy a new valve to your liking and stick it on there.
