Re: Delco Light Water PumpXX
Delco made a lot of different pumps, both shallow well, and deep well. They made them in piston and jet.
I don't know of any one with a serial number list for Delco pumps, so dating will be difficult.
As far as I know they only painted them in black or orangeish red.
A picture is worth a thousand words, a person once wrote. If I had a picture I could give you a pretty good guess as to the color and date.
