2g Charcoal box removal

[Khadgar]

Ok so I've pretty much have all the vacuum lines and solenoids out as shown in the Taboo speed shop diagrams. I have the charcoal canister out along with my EGR blocked off, my question is I have two lines coming out from the firewall, the smaller is just slightly larger than the vacuum lines coming out of the car, and the other is large with I'm guessing a ~1/4th" ID. I know one of these is where the gases from the tank is released and I'm guessing it is the larger of the two, but what is the other one for and what exactly do I do with them? By the way this is a 95 with the canister under the battery.

Thanks

Dude, this thread is from 2004!

Anyways, to answer the question - You leave the one for the gas tank vented and plug the other line. I capped both of them for a day and then took the caps off one at a time. The one that has gas fumes coming out of it after you take the cap off is the one that you leave vented. I put a breather filter on mine.

FYI - The 98s are not the same as the 95s. We have the charcoal canister under the driver side headlight.

I'm concerned about venting gases into a hot engine bay? The way I remember it, there are three lines going to the fuel tank, the feed , the return and the vent tube. I blocked off my vent tube. I'm not supposed to?

No, you are not supposed to block off your vent tube.

Blocking off the vent tube will result in more pressure in your gas tank. You can notice this sometimes when you fill up gas and removing the gas cap causes a hiss.

and nothing will catch fire?

I hope nobody minds me reviving this thread. I just try to search first and then post. This is what I found, and if there were pictures they would have helped.

On my cannister, on the top, there is piping for two hoses to attach. One of them says AIR and the other says TANK. My TANK one is connected and I could not find the tube that went to AIR. For all I know it was missing when I got the car. There is a hose going to my CAI (also installed when I got the car) that comes from, what I think is, the purge solenoid... or whatever it is called.

Regardless, my tranny isn't working, so I've got bigger fish to fry right now, but once it is done, I hope to remove the EVAP setup or fix it...

It has been 3 years and my car hasn't blown up.

I had the same concern when I capped mine off about 5 years ago and haven't had any problems with it. I hated smelling gas all the time with it open. I just stuck one of those little rubber caps that come on new things you buy over it, that way if it built too much pressure it would pop the cap off. It's still in place and it gets hot as hell here in the summer

I guess the only performance concern i would see is if you were using mass amounts of fuel pretty fast and created a vacuum in the tank that starved your fuel supply out. But how likely that is, i don't know.

I was wondering if this vent tube being left open is the cause of my cel evap code??

 

[stonetalontsi]

i have done some reading on this and i never really got a straight answer. some ppl say it will and some say it won't. If i take my canister off will this affect my emissions.???

sorry for jumping in

Yes it will throw a code unless you have link, then you can turn it off. I live in Fla so we don't have emissions inspections, and after I removed my canister I routed the fuel gas line underneath my car so the fumes don't come in

 

[docb002000]

ok i am not worried about emissions just wondering since i dont have dsmlink and I was to put a one way check valve on that vent line would it stop the cel

 

[JRoX85]

nope
