I had to modify the jug by drilling a hole in the side, and screwing in a tubing connector. The hand pump already had a connector for tubing.
Here is a video of a peep inside the chamber. You can see it grow as the air is pumped out of the jug, and when the air is let back in you can see the peep shrivel up.
