I had not thought about pin holes in the pick up tube, and I can't see it to
find out.  That is a definite possibility with a 45 year old tank!  I'm
going to put a fuel hose from the pump into a gallon of gas and see how the
system pumps tomorrow.  If it pumps fine, then it is definitely on the
suction side, which means a new tank.  

I just hate to replace the tank with one without baffles.  I'll take it to a
radiator shop here that rebuilds fuel tanks and see what can be done before
I do that.

   Can you see the pickup line inside the tank?  Perhaps it has rusted
pin-holes. If two or more pumps work OK, but pump more than they should
before delivering fuel to the carbs, the problem must be in the suction
