Jeff,

I've installed it. I dug through my box of hose sprayers to find just the
right one for filling. It's long enough and narrow enough to fit in the
opening and push through that rubber flap. If the pressure causes a backup,
that water comes back out through the little overflow tube on top. I added
a quick-disconnect ball valve before the sprayer head to better control the
flow of water. It worked a lot better than anything I've ever tried before
with the old outlet.

It looked sort of like the one here:

The rubber part helped it seal in the opening.

Good luck!
