Hello,

I was checking my engine bay in my 1987 Camaro RS and noticed a broken vacuum line. The line comes from the Evaporative Emission Canister to the rear of the the throttle body. The area that is broke is just under the throttle body on a bracket mounted onto the valve cover just in front of the oil cap. (see pictures) The vacuum line from the Evaporative Emission Canister is rubber. The line that comes off the Evaporative Emission Canister line to the rear of the throttle body is a hard plastic line.

How hard is it to fix and what parts do I need? What effect does this line have on the engine if any?

Thanks Tim

That plastic hardline was a bad idea from day one, in my book. It lasts longer than standard rubber line but when it gets old..... snap! And there's no way to fix it, really.

I just remove it completely and run fresh rubber vacuum line. Trace that hardline back to wherever it hooks onto the TB or intake and look at the size of the hose nipple. Chances are it's got a larger rubber end on it and a "standard" size vacuum port. If that's the case you can just get some regular rubber vacuum line and run a completely fresh piece from end to end.

Your broke right at that little connector, which you wont be using any more once you run the new line- you'll just do a straigh shot from the intake to the canister. You can still keep using the connector for the larger line that's also attached to it, though, if you like (or you could run a new fresh one for that as well).
