Randy,

Did you get your fuel pump working?

When I installed my Bosch fuel pump, I got the polarity wrong.  I could hear
it run, but it pumped no fuel.  I confirmed that polarity was the issue by
running the fuel pump off a 12V cordless tool battery hooked up with
alligator clips to the connector on the top of the tank--with the polarity
"backwards" I was then able to start the car.
 
Rather than dive back into the tank *again*, I just reversed the polarity of
the two wires to the fuel pump in the wiring harness in the trunk.  Solder,
shrink wrap, good to go!
