If and when I ever get this 3rd Edition of the Gas Pump book printed, one of the new sections pictures approx. 175 outside sight glasses.
Let me interject something first. Recently someone asked me why did I use pictures from original factory literature instead of pictures of recently restored pumps. This is easy, the reason is that the factory pictures show, in this case, the original outside sight glasses, not replacement ones that someone put on because they wanted the pump back in service more than they wanted the "correct" sight glass on the pump. Who knows why certain things were added to pumps.
If you email me the model numbers of the pumps I post the sight glasses I determined to be the original ones used on the pump.
