There are only 2 different rods: the "normal" one and the shorter one 
for beetles with alternators.

If you had the short one, the engine would never have run. I have 
heard, however, that modern replacements from Brazil did not get 
hardened and could wear down slowly, becoming ineffective. That may 
be what you had. Unless your second rod is stuck in its upper 
position, I don't know of any reason why it doesn't move.

As Robert said, it's important that the rod be free in the flange and 
that it be the right one. You are supposed to adjust the height of 
the flange by installing extra gaskets under it until the rod moves 
thru the right range.

You should also check the rod for warping by rolling it on a flat 
surface.

I have a couple of old, presumably OG, pump pushrods here if you need 
one.
