Replying to BROKEN PVC FIX?

A few weeks ago a piece of plastic from my PVC double barrel came off. Then a week later, i threw a switch up and landed on the chipped piece, and broke another piece off. So now i have 3 inch missing piece of PVC on one of my pipes.
How can i fix this? I cannot find all the missing pieces of PVC. I tried duct taping the inside of the rail, and nuking it with Gorilla glue. That didn't work.

So how does everyone here fix their fucked pvc rails?
