Thanks to all who responded, both privately and to the list.  The
general concensus was that my initial theory about "indentations 
in the gasket" was completely wrong, and in fact I've fixed the 
immediate problem using the original gasket -- it looks like the
leak was caused by not having the hose assembly screwed down 
properly.  I had tightened it until it felt like about the same 
resistance as when I opened it, but the resistance I felt was due 
to a small section of the nylon shell I let cover a length of one 
or two of the threads on the bladder side.  I felt rather silly 
for not noticing this sooner, but anyway the solution was to work 
my way around the connector, being careful to tuck all the nylon 
below the bottom thread.  It was fine for diving this weekend.

George, I'm interested in your comment about replacing the whole
assembly.  What works best?  In previous notes I think you mentioned
Sea Tec wings needed "fewer modifications".  Is the hose assembly 
one of the modifications you alluded to?

JT, as to why I took it apart... I just wanted to understand it
better, and supposing it was a relatively simple piece of gear I 
thought just taking it apart and looking at it was the best means 
to that end.  I still think that's true.  It's safe to say the 
"real" problem here was that the gear's simplicity was being 
exceeded by my own.  ;-)
