Thanks, guys!!! I'll check all these scenarios out and see what I can find. I thought about the tank vent, even took the gas cap off while waiting on the tow truck- it still didn't pump fuel. Would it take a while to equalize pressure (vacuum) before it would pump?

Also- now that I have the electric pump, is it any problem to just leave the old mechanical pump attached to the block pumping air, or should I remove it and get a cover plate? I tried to use both the pumps in tandem but the elec. pump wouldn't
pump through the mechanical pump if the engine wasn't running.


Edit: thinking about the vacuum issue- when I took the fuel hose loose between the tank and pump, while sitting on the side of the road, there was plenty of fuel flow to the pump via gravity. The pump just wouldn't move it. Could the mechanical pump get an air lock or something?
