The break was at the rear of the piston, where the air hose connects. (Marked for your convenience)
The plastic nipple on the piston had cracked. I replaced the hose nipple with a half inch length of 1/8" brass. I drilled out the hole at the back of the piston so the length of brass fit tightly (I drilled one size small). I sealed it with hot glue (goop would be better, but it's all I have).
The broken nipple was still in the hose, and not coming out, so I cut it off. 1/8" brass fits perfectly inside of Wildfire hose, a nice tight fit.
Here's the finished fix:
