I took off the base, put the piston at the highest point, and then

non-petroleum swimming pool supplier Teflon grease you'd previously

How was that insufficient (as asserted in your last)?

It was your use of the word "swabbed," Skip, instead of "smeared."
Knowing your penchant for meticulous detail, that produced a vision of
your using a Q-Tip to meticulously coat the cylinder with a thin coat of
the grease--and then you asked if you should also put some on the
o-ring...vs giving it a healthy squirt and using whatever works to
spread it all over the inside the cylinder, which would also coat the
o-ring and everything else on the pump shaft when you pumped. You can't
use too much of it--it's water soluble, so any excess that's forced out
won't hurt anything and would actually benefit any y-valve in the head
discharge line, but you can use too little to last very long...and it
appeared that's what you'd done.

And unless you "swabbed" at least a tablespoon of it, I'm still not sure
you didn't.
