Busted this (blue tape) line removing the plenum. What are my options? (Besides the obvious)

I would recouple it with a short section of tight fitting vacuum hose. I might also take a trip to the junkyard as most GM cars of this era have tons of that hard line and various rubber connections you might find useful for a repair or modification.

Autozone or Advance have a vacuum couplings. Tack it in with 3M adhesive--black.

Thanks for the suggestions guys I will take a look, but in this case couplers won't work. The line was broken in two places both were line bends.
I think I have three options. Replace lines, fabricate new, or somehow eliminate the whole thing?

Been a while, but I believe it was AutoZone that had that plastic line packaged in rolls. The idea is to warm it with a heat gun to shape it as needed. When it cools it holds its new shape.

As for eliminating the secondaries, far be it from me to discourage you from that. After "plenum diving" to fix different vacuum problems, I eliminated them when I did my top end P&P and port matching. Nothing but GOOD came from pulling them, but it will require a chip calibration and a simple hard wire precaution on the POWER switch (on 1990 Zs only).

What is involved in calibrating the chip? I believe that the last owner installed some sort of performance chip. My car is a 1991.
