How to remove charcoal canister and not get CEL?

[Kroggers]

Here is a picture from my completed removal project. In the future, I will probably remove the two blocked vent lines, but kept them in there for now - keep it simple



I pulled everything out and just let the tank vent to atmosphere under the liner - you can see the vent line attached to the metal bracket.

As for smell in the garage - my 911 (1978 SC) also vents to atmosphere and I do not get any heavy petrol smell in the garage, but maybe it does not get hot enough over here for me to notice it?

I have not had a chance to test it yet, but I did start the engine and let it idle for some time and I did not get a CEL from having removed it all.

My car was not the same as the diagram that Brad posted. I Think the US cars have more stuff in the system than the cars over here. I for instance did not have item 5.

Kroggers, just thought you would want to know that one of the hoses you have blocked off is actually a vent hose that runs all the way to the rear of the car and exits under the the trunk floor just behind the bumper (maybe behind the foil heat liner in your case. In my case the heat sheild has been removed).

I found the vent pipe by blowing compressed air into both of hoses that are blanked in your case. One of them does not allow any air to move, the other does. With the one that does you will hear the air escaping at the rear. By your photo from earlier the vent pipe will be the green arrowed hose that previously attached to the top of the canister. By the diagram provided by Brad this is the hose that exits out the top of 6 and disappears to the top right of the picture. If you have not upset there original positioning it will be the lower of the two you have locked off.

I simply looped the hose from the tank (red arrow from above) with the one that exits the rear (green). The other is still blanked until I figure out how (or whether) to remove it. From the diagram we know it runs to the "tank vent valve" but I have no idea what that is or where it is

All of this was prompted by the fact that I was getting a smell of fuel in my car (which I had previously set up exactly as you have) whilst on the track. Hopefully this should fix it.
