Just removed the charcoal canister....
I plugged the line that comes from the fuel tank...
should it be left open or is it safe to plug?
Thanks

 

????
also want to know

 

leave it open

 

dont cap it, vent the line to the atmosphere.. you'll smell fuel every once in a while, but it's no biggie..

I should have taken my own advice that I've dished out so many times.. and just searched!!
There is a big long thread on this already- but with many opinions.

One guy said that there is a releif valve at the tank, and if the vent line is capped at the firewall, it will vent at the tank anyways.

I would MUCH rather have it vent at the tank than under the hood.

What about running it from the tank up to the area round the filler door?

Why leave it open? Too much pressure buildup if capped?

 

whats the advantage of removing the CC anyways??

 

Besides a cleaner engine compartment, I can't think of anything.

 

On jacob cartmills NA FC, we just cut the lines off the canister, yanked it out of the engine bay, and then plugged all the lines. His is running fine so far...

 

pull off all of the lines, and shove a golf tee into the line that goes back to the gas tank.

 

Im pretty sure there are better things to shove in there than a golf tee.

 

I would only suggest to plug the line, if you get a vented gas cap, other wise pressure will build up in the tank.

 

Ive been driving without a charcoal canister for close to 2 years. My impressions? I wouldnt do it again, and Ive even considered putting mine back on. One, there is not a vent or pressure relief at the tank. My tank gets pressurized, sometimes quite a bit. That affects the mixture because it raises the fuel pressure by how much pressure is in the tank. In other words, I was running WAY rich when it was hot outside.

As far as not capping it, it wouldnt have any of the above problems. But, I just dont feel safe with gas vapors in/around my car, especially when its 100+ degrees outside...

 

Vented gas cap my friend vented gas cap.

 

why not have it vented outside the car,and not inside the engine bay? jus have it pointed down under the car, sounds good to me.

 

There is a pressure relief valve at the tank. It's called the check-and-cut valve and it mounted under the car near the tank. It's inline with the line that vents the fuel tank vapours into the charcoal canistor. Its purpose is to ensure the tank does not experience either positive or negative pressure. It's a 3-way valve, and if the tank pressure is ~1psi above or below atmospheric it will vent through the third leg which is open to atmoshpere.

If your tank is pressurising, this valve is probably faulty and should be replaced. This should fix your problems.

As for charcoal canister removal, I'd leave the lines open, but I'd disconnect the line at the check-and-cut valve. This way any venting to atmosphere is done at the tank, not in the engine bay. Leave the check-and-cut valve in place and working, so the tank's only venting when needed.

Note that there's no advantage to removing the charcoal canister, and I'd only bother doing it if I were removing the vacuum spider, solenoids, purge valve, etc. If you need to pass a visual emissions inspection, absence of a charcoal canister will almost certainly fail you.

 

mine is still there. but the line that went to the engine is now just vented down in the fender. I figured that was better then remving it and just venting the line from the tank.

 

Ill have to check into that, Jason. Thanks.
