I just reinforce the inside of the broken nipple (whether it's on the tank
itself, or one of the valves or vent tees) with a snug fitting piece of
metal tubing.  Then I use a 'cut and knead' epoxy putty to make neat
exterior reinforcement.  Reassemble as normal when hardened. Works good,
lasts a long time, stronger that stock.  Should hold up to vacuum, pressure
or exposure to fuel, oil, etc.
