Thanks.
I would see/smell leaking or defective fuel seals, o-rings, leaking FD, injectors wouldn't I? And the other items would affect the normal operation, like mixture, air leaks, timing, and ignition. And again, a shop checked the residual fuel pressure and said it was fine. Car runs fine - only when hot, it's hard to start. No leaks visible, no gas odors.

I am curious if the OP resolved his problem and what was the cause or fix.
