Now the plot sickens.  IF I hear a pffft, AND the seal is working
correctly THEN the pffft is merely filling the oddly empy 'rest of the
system'.  Since the pffft is often no more than a pfft, the regulator
may have a 'seep' that slowly empties the rest of the gas plumbing.
Soap spray on the way after I get a look down under for obvious
culprits.  No sense replacing perfectly good functioning parts even if
they are victims of old age and decreptation, horrid age spots, and
pattern baldness.

Pensionerd.
