Even if the other one isn't original, it may still be an old enough replacement to have been a rebuilt original unit or a Made in USA replacement. Still worth keeping for future rebuilding.
My "original" glass bowl fuel pump is actually an Airtex unit, probably from the 1980s or so. It was rebuilt and functions as it should, not like these crummy Chinese ones you buy now.
Otto is right on here. The fuel pump that came with the motor is a
Made in USA fuel pump and works fine. I was just afraid to put it on when
everything else is brand new. After a new one failed, I think I may use the original
and keep the Chinese made one for a backup.
