Saginaw pump fittings

No, inverted is not the same, although the thread could be. So far as I know the O ring fittings were "proprietary" that is, not SAE If I run into this nonsense I'm going to simplify my life: Take the fitting apart at the pump and braze (silver braze) a JIC / AN fitting or some such, "something" I can "get"

I realize these girls are getting old, but some popular "parts store" hose selling strategy is to decrease stock by selling both ends which screw into a hose of some length. You should be able to buy those separate. You might be able to build on that. There were several replacement brands which did this.
