Rob said his tank had developed a leak. That would mean that there had
been gasoline in the tank. I don't think anyone would suggest welding
a used metal tank, how could it be any safer with a plastic one?

Doh! I realized that, right after I hit send. I'm sure I would not have
done that if it were sitting there in front of me!

A soldering iron would be safe, and almost as effective at doing a little
plastic welding. It is kinda' fun, if you have ever done it before.
