I have found the majority of the parts I have needed to complete the "rustoration" of this pump. Thanks Tom Buckles!
However i still need a piece of the internal piping.
The pipe in question runs from the meter to a common manifold shared by the hose outlet and the sight glass. Each end of the pipe has a three sided flange with three attaching bolts. This pipe is unique to the Wayne 600 model.
I have attached the manufacturers diagram with the pipe highlighted.
Let me know if you have one laying around. I know many collectors gut the internals of the pump so I guess there has to be one some where.
Thanks so much for any assistance.
