I have been experiencing a strange new problem with my TBird.  It is very hot here in Central Florida right now.  We have a small car show every Wednesday morning in a paved parking lot. Three times now I have had a problem starting the car after it's been sitting in the heat.  My car is black and you could fry an egg on the hood.  The engine turns over, but it acts like there is no fuel. I pump the accelerator and nothing happens. Eventually the engine starts and it runs perfectly.  So far I have not had the problem when the car is in the garage or at any other time.  I have a Holley 465 with a 1957 "B" intake manifold. I haven't looked down the carb to see if I'm getting fuel, but it's very intermittent. Do I need an electric fuel pump?
