While re-installing my polished plenum and runners I accidentally broke the plastic vaccuum tube that connects to the right side of the throttle body, and the smaller one that connects to the bottom left side and forks off to the manifold. they both work there way down into the front left of the nose where there is an emissions canister.

I have tried to patch it with hoses as I am told from gm these are discontinued parts.

are those two lines real important, or are they just emissions crap?
are there any consequenses to them being leaky or disconnected?

does anyone know of a place that sells the proper plastic tubes?

thanks

There are several things you can do I like to use alum or copper tubing they make it that way for pilot lines on cooking equipment, just use some small bits of rubber tubing at the ends. Also, you can buy the plastic tubing from a large truck repair shop it is rated for high temps. :thumbsup:

^^^Good Info^^^

Just another add on......if you can't get a hold of anything NICKO suggested, you can get black plastic tubing at a local fish store thats used for air pumps in aquariums. That should do the job also and can be cut to size. :thumbsup:

Mine are capped off where they would connect to the Evap canister the canister was removed when the C-5 nose was installed and I have no codes and no problems. Evap system purges gas fumes from gas tank and sends them to the intake.:thumbsup:

I did the same thing to my lines and I am glad to hear that I am not alone. I will try the copper tubing . It sure broke easy.

you can buy the tubing at advance auto parts, the tubing and the connectors to go onto the end are in purple packages and I think they say "air tite" on them. the tubing I think even says emissions tubing on the package. then they have all the rubber L fittings and straight fittings to put onto the end.

Also, look at the Motormite Help products section in your local auto parts store. They carry a lot of those vacuum check valves, tees, etc...

I have completely deleted all the emmissions stuff on my car. I still have at least one complete set of the vacuum lines and might have part of another one due to the fact that I have two extra tpi motors in my garage. SC has no inspection, so I don't need all that crap. might be easier to go the route stated by a couple people above, but if you need it, I can send it to you.
