The engine started after only a couple of minutes the first time and then
started easily after that. As a matter of fact, it is stopping the engine
that has been curious. I will turn the fuel pump off but the engine will
continue to run for several minutes after the pumps are off (I can still
kill the system by flicking the coils/injectors off but I believe this can
lead to flooding and is "bad form"). Actually, the engine really sound nice
just before it does stop due to fuel starvation....yeah, I think I am
running really rich 'cause when I lean, it really smoothes out.
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?
