OK to remove charcoal canister??

[marcesq]

I was replacing the shocks today, and removed the charcoal canister from the engine compartment. After checking the factory manual, I see that clean air goes in mixes with vapors from gas tank and everything is returned to the air box.

Is there a problem (like explosion, etc) if I run the line from the gas tank directly into the air box.

Thanks as always for the help.

either nobody knows or nobody cares to help out...or you already found your answer.
I always thought it as for cooking in a pinch.. like when you were broke down somwhere..... well that is unlikly.. so its proboably ok to remove it.

I don't know if I'd want a straight line of vapor from my gas tank all the way back to a backfiring airbox.

That just seems like a bad idea.

If I were you I'd either keep it the way it is (which is probably the best course of action) or get rid of it and vent the tank in some other way. I don't have a charcoal canister, the PO had plugged the line so I removed the sealing ring from the cap and vent that way. Seems to work ok.

jkeyzer,
I just did the same thing to my 87 carrera slant nose. i had just finished relocateing the oil cooler into the right rear brake ducts
and no longer had room for the canister. I just stuck the little
line into the big one and zip tied them in place. Took it for a 45min drive yesterday no ill effects that i could tell.

I have the same part, but mine has two large hoses coming in at either end, and one small one exiting at one end. I found a little plastic three-way connector at NAPA, am planning on hooking them all together just as they were with the charcoal canister, only using this little connector instead of the canister. I'll let you know how it works, when the car finally gets back on the road this spring (probably too late to help, but oh well)

By venting the gas tank directly into the air box I suppose you could confirm no ill effects by introducing a flame in the air box and see what happens.

What's wrong with the charcoal canister? Too heavy? I think it'd be safer to vent it to atmosphere or even plug it. Make sure the gas cap is vented though.

I was confronted with the same proble. I removed my canister on my 73.5 T and after filling up the tank with gas, the passenger
compartment smelled like someone poured gas in it!!!!!!!!!! Awful.

It is still connected but I did remove and plug the opening on the fan housing and the air box in which both lines from the cannister connect. I cut the lines (they more or less deteriorated) as they came through the fire wall, but did not cap so ventilation takes care of any stray fumes. This has been for the last 9 months and I encounter no problems or strong odors. I would leave the cannister alone in the trunk.................with the lines attached. Its not that bulky to be that much of a burden in the trunk.

The charcoal cannister is part of the fuel emmission recovery system. If you over fill your gas tank the gas expands and the fumes are eaten by the charcoal cannister, then the cannister is cleansed when the motor runs, so it will be fresh for the next time it needs to eat fumes. OTTO

I would like to thank all of you for your thoughts.

Generally, there is nothing wrong with the canister; however, it was in the way when I changed the shocks so I got to thinking what if ??

My can has 2 large lines, one to fan housing, one to air box. 1 very small line from front of car. Manual says it is from expansion tank.

If you all see any mushroom clouds coming from the DC area, it might not be terrorists

Thanks again.

Good thing the car wasn't running yesterday when we were bleeding the brakes!
