Because it makes little sense without it, I apologize for leaving in
the entirety of the conversation until my followup:

For a pump which is already in service (and was rebuilt with nearly all
of the supplied grease going onto the piston O-ring), this is how I
regreased it:
I took off the base, put the piston at the highest point, and then
thoroughly swabbed the entire cylinder (since it was difficult to
control, I did the part under the stroke a bit, too) with the
non-petroleum swimming pool supplier Teflon grease you'd previously
recommended.
You went to all the trouble to swap the inside of the pump? You could
have just put a VERY healthy squirt of the grease into it and pumped a
couple of times to spread it all over the in side of the cylinder?
Swabbing leaves a very thin coating...whereas a good squirt of it gets
onto everything in pump...any excess will flush out without any harm to
anything.
I've got terminal density, I think, as I recall your recommendation to
this effect (long) before. However, on followup then, it was my
recollection that the PHIIs don't let you do that.
So, assuming I misremember (happens more and more lately), where,
exactly, do I put this heavy squirt? As I (think I) understand how
this thing works, if I were to take it off the base as I did, and
merely put a large dollop of the grease in it, reassemble, and pump
away, it would immediately go out the joker, other than that which
managed to scrape against the sides.
Or, is there somewhere else I put it? As I did it, I put a pretty good
layer around the cylinder. My first attempt (years ago, now) had me
putting it down the flush/dry valve, and the output to the bowl,
because I couldn't see anywhere else (which was supposed to be so easy)
which, of course, thoroughly lubed the ball and seat and made the seal
not very good there.
So, apparently, I have no picture at all of how to put in the grease of
which I now have a very sizeable (well, at least as compared to the
stuff wihch comes with the rebuild kits) tube.
Pardon my density on this matter. I'm pretty sure I could field
assemble, in the dark, blindfolded, one of these units, so I think I
know where stuff is. How do I lube this better than I did? Take off
the base, put a tablespoon of grease on the bottom of the piston? Or
on the flapper weight? and expect it will make its way to the O-ring
and walls? Or through one of the two ball valve locations? If
swabbing the cylinder is trouble, I can't imagine I'm supposed to
disassemble the piston/cylinder, which would be necessary to grease it
through the top of the piston, the only other possiblility short of
removing the air valve of which I'm aware.
And, of course, if there's a simpler way, while I don't mind (I've got
long fingers) doing it, if I don't have to swab/slather the cylinder,
I'm all for it :{))
Thanks, as usual, from your densest student...
