As most people know, the high pressure connection on this type of pump is
female. For some reason, all the OEM type replacement hoses have a female
connector also. At Napa, they offer a universal hose also but it has a union
at the female connector. They didn't have it in stock so I couldn't see what
the union looked like nor could the counter guy find a connector that would
work. I have no idea what the nomenclature is for the union in order for me
to try to find one. Does anyone know any way to find out what this
union/connector would be called or know any way to find one?  I even checked
with a Chevy dealer but they were no help. Thanks in advance if you can
help.

I can email pics and text to describe these items if needed...
