That wasn't the fill plug. That was the pump valve.
Small valve to bottom large ball on top. The spring usually goes between them.

thanks Steve , i tried that and didn't work , i put the small ball 1st then the big ball then the spring and plug, it WORKS , thanks for the idea though ,
Depends on which factory and work group made it....
Here's a diagram. The little ball goes in first, then the small spring, then the big ball, then the big spring. I've seen this in a couple of jacks:

Of the same dimensions, file size and a substring of the same file name, and excerpted straight from the site I had provided:

Good work.
