Fuel Pump

[MICHAEL JONES <jonesmp@prodigy.net>]

  I have what should be a simple problem that is driving me nuts. A friend was 
doing some work on my 69' C and found the fuel pump did not work (car had sat 
for 5 yrs). I then put a new pump in that I had for about a year. Didn't work. 
I checked the voltage and had 14 volts to the pump. I put in another pump that 
I bought a few yrs back at an auction and it didn't work. Am I overlooking 
something simple or can you have that many SU pumps not working?
