Charcoal canister question
I'm in the middle of redoing my greddy setup, last night I noticed the line that runs off the bottom of the canister has a plastic nipple broken off into it and was hanging freely.
What's this line do? does it vent to atmosphere or route into the intake manifold.

Its part of the evaporative emissions system, shouldn't throw a code on OBDI cars. You might fail emissions for high HC counts though, but dont quote me on that one. Emissions class is kinda a blur to me now lol.

It shouldnt pull a CEL unless you unplug it or don't hook it up to your exhaust, and then its only some cars it seems. The whole EGR system is a big pain and eyesore IMO. Certainly glad I was able to get rid of all of it.

Hello BenR, to answer your question, I took a look at my parts car last night and found that 3rd line that routes off the bottom of cannister is routed to the front subframe and vents to atmosphere. This is designed to supply fresh air to the system. Apparently 1.8 cars do not have this line as they get the fresh air from the grid on top of the canister.

Actually, we do have them. <G> My car has the vac line going in off the intake manifold, a second line going out through the top.... which I believe goes down to a hard line, which then connects to a rubber hose, which is supposed to be attached to the subframe (goes internal to vent to atmospher). Although, I'm doing this completely from memory, since the car's at home in storage.... (I know I have the line to the subframe, since I had to tie it up out of the way. <G>)
Maybe it's the ODB-II cars?
