In any case, I had a few minutes yesterday to connect the fuel pump on the bench, or the top of the trashcan, if the truth be known. I had a plastic can of what is technically old gas, but it was fine for this mockup. I had to prime the line by forcing some fuel into the intake, but once it was there, it worked great.
A long time burning question was how much current the pump would pull with the system under pressure. Looks like 3.46 amps, about 1/3 of what I feared, so I can go on with my electrical life.
