Chris, sounds like you have something expandable in your fuel system that
allows it to continue running.  Is there a lot of rubber hose? air bubble in
a fuel filter or length of sample tube (like to a fuel pressure sender)? a
large pulse damper?

I know exactly what you mean by running ultra smoothly right before it
finally runs out of fuel.  I have been hoping that the snubber fix would
allow it to run smoothly all the time.  I assume you have the new snubber
fix as well.  Please tell me that you have just neglected  to re-tune idle
since getting the unit back...  Or am I just hoping for too much from the
injector circuit snubbers?
