I had a job done to my car which involved welding and the heat caused the evap emission vent lines to melt and are now cracked. What do they exactly do? My dealer wants to rape me on the fix but the place that did my work is fixing it up for me... Im glad they are so willing to help and not just throwing me aside. I dont want to mention the names of anyone or the work done, but was interested in some knowledge on what they vents consist of, how much people think the fix would be, and if its bad for the car which i was told wasnt bad but could allow vapor to escape from the fuel tank... many thanks for any input

It's part of the required emissions equipment to control vapors from the fuel tank. It's a quite complex system that recovers and burns the volatile vapors from the fuel tank, all the while controlling and allowing enough air in so the fuel keeps on flowing. If the tank was sealed, it'd eventually reach a vacuum as the fuel was consumed and no amount of pumping would suck any more out.
The whole fuel system on the C5 is quite complicated - admittedly, I'm not entirely sure how it works. There are two tanks and fuel is continuely transferred between them and the engine and back to the tanks, there are seals and vents and vapor cannisters and solenoids and all kinds of hoohah in the vapor control system too. Even the cap is part of the system. You'll get a check engine light if you don't tighten the filler cap all the way when you gas up.
It's pretty fortunate that the welding didn't set off a fire!
Hopefully, they'll be able to repair it without issue.
