I am still a relative newbie so please forgive me if I am totally off base with this, but could you attach the one way male check valve foster fitting to a female foster quick disconnect and attach the female end to a male foster of the tank (essentially a male to female standalone adaptor)? My tank only has a male foster that then attaches to a double female hose that I got from Joe Brancato. If that worked, it would be a very convenient and quick connection for only filling the tank. Thanks.
