I don't have any literature on this pump, I only have the picture that is on pg. 230 of my new Gas Pump Bible, identification book. It shows two sight glasses and two hoses, so it operates from both sides. I don't know if there was a single.

One more piece of information, this pump was not patented by Fry, it was patented by Wayne Pump Company.
