Steve,
A fellow 9A builder loaned me this thing that he bought at a plumbing supply
store. I'm not sure what you call it, but it's a metal and rubber plug with
a wing nut on top that you twist to make the rubber plug expand to the
diameter of the pipe you are trying to plug. The diameter of this thing was
just slightly smaller than the filler cap, so it fit into the opening in the
tank almost perfectly. Anyway, I took a latex glove and put it over the
plug, then twisted the wing nut until I had a good, tight fit. I then tested
the tanks with a manometer and from what I can tell, there weren't any
leaks.

My filler leaked as well. I ended up using the balloons that look like
catepillers (sp?) as opposed to a smooth look. Blow up the balloon with
about half of it inside the tank and the narrow part of the balloon at the
neck and the wider parts on either side. This seals the opening very
effectively.
