Fittings on rotationally molded tanks are attached by
first cutting a hole then spin welding the fitting.

The fitting is held in a chuck attached to a motor,
then pressed against the tank and spun until friction
melts a bit of the fitting and tank.

Try some experiments on a junk tank to see what'll
work. A Yahoo search for spin welding plastic turnes
up lots of info.
