Thanks to all who responded to my tank question, and especially the

answer from JDeRyke below.  I had already replaced the pump, installed a

new fuel filter, and pressure/vacuum tested the lines.  Then I realized

the problem had to be in the tank.  



As you suspected, I do have the old welded tank.  Although it had 1/2

tank of fuel (determined by the wet wire method and visual inspection), I

couldn't understand how the fill tube could be empty.  I air pressure

blew the line and rodded, but didn't know about the sock at the bottom. 

Everything now seems to work.  Thanks again.
