I had/have second thoughts on the o-rings.  Part of me thinks they
can let fuel leak, and part of me thinks that, since they are just a
push fit, they don't really hold in gas but rather keep air from 
leaking past them.

CCing the V8 and quattro list for a sanity check:

Q. Do the fuel injector o-rings seal against fuel line pressure leaks, 
     or do they merely seal against air leaks? Or both?
