Carbon Canister -- Where Does Hose #20 Go?

[Ben Carufel]

I don't have an E30 with a carbon canister in front of me, and it's something I need to retrofit to my S50 E30 in order to pass California smog...

So I'm trying to figure out this diagram. From what I can see, it's very simple -- the one hose comes from the expansion tank (which I recall being in the RR wheel well?), but the hose exiting the carbon canister is a mystery to me.

It's #20 in the diagram below. Where oh where does it go to on an M20? How about on an S50?

Um, is kellie not picking her phone up? HAHAHAHAHAHAAHa.

That barb on the charcoal canister is connected to a hose that connects to an electric check valve, which then goes to the rightmost barb on an M/S50 throttle body. The electric check valve is actuated by the wire that is paired with the HFM connector.

If you pull the rubber boot back on the connector, the wire colors should be BRN and RED/WHT.

Fred, by "rightmost barb" do you mean the one that is farthest towards the rear of the car when the throttle body is installed? It's literally right next to the bracket that holds the throttle cable in place?

[FredK]

yup, that's right.
