They would be used to hold the drive gear on a GM distributor amongst
other things. Last time I used one was to install a large yellow knob
on a PP1 valve. That is a truck air brake valve. Typically, auto parts
stores will have a drawer with a selection of these pins.

==========================
Thanks for the information but not even close. This is a long thin
ceramic needle-like thing, more like a piece of cut coathanger but is
made of ceramic material. It goes through the impeller to keep it
spinning in the middle of the impeller well. It's stabilized at both
ends so the impeller can spin and not actually touch the sides of the
well.


Any chance at a pic??
=============================
No. I tried to find replacement parts for Tetra pumps and never came across
them, no less a pic of this ceramic shaft. It was just a thin ceramic rod
that looked like a piece of white coat hanger and was about 4" long. The
ends were clean-cut and the surface was rough like flat paint (IOW not slick
and shiny).
