Vacuum line connected to throttle body

Hi I accidentally broke a pvc pipe when I was replacing my fuel injectors. I’m having trouble finding the hose online. The pvc line connects to 4 different lines. One goes to the pvc valve and another goes to the canister.

Re: Vacuum line connected to throttle body

PVC is a type of plastic, often used for plumbing pipe. Generally white, but other colors could be used.

PCV is an emissions-control device that's been used on vehicles since the early--mid 1960's.

Many of those (fragile/brittle) broken vacuum tubes can be spliced back together with rubber hose of the proper size. Depends on how/where they break.

Maybe, just maybe, if that was a 3rd gen Camaro or Firebird engine, we may be able to help. Right off it is a port injection system, not TBI.

Go to AutoZone(or wherever) and buy some similar sized rubber hose (and whatever T fittings, etc. you need) and route it in place of this one. No need to buy a hardline.
