Charcoal cannister lines, what to do with them???

[Stoner]

I have searched at least 7 pages and I cant find the answer that I am looking for. I also know all the ill affects of removing emissions so please spare me the bashing.

My question is what to do with the vacuum lines and whatever those little valves connected to them. I have seen some people saying to pull all of it and leave it venting so the tank doesnt build up a vacuum.

If this is correct how do you vent it. Just leave it unplugged or should I re-route it somewhere else, put a filter on it, or what?

Thanks,

peronsaly i blocked my line coming from the fuel tank because i could smell gas while working on the car.

I plugged mine too.

I will assume that you have not had any trouble by capping that line off. Also did you just ditch all those valves or whatever they are, their are 3, I believe. The lines off of them go up behind the intake mani, i assume that those are gone as well.

One more thing, did you just plug your air intake where the line used to go to the charcoal cannister?

Thanks,

I plugged the fuel line and the intake holes where the line used to go, no problems.

I removed the whole EGR system from my Talon, and all the solenoids and valves and hoses go.

Make sure you plug that line, or else your gas will be evaporating into the atmosphere all the time and your gas mileage will seem to be horrible. I'd leave the EGR hooked up if this is a daily driver. Trust me you'll miss the 40 or so extra miles you get out of every tank if you get rid of it. It's closed at WOT anyway, so you're not "heating the air that your intercooler just cooled". The only other excuse you'd have to take it off is that you "don't like the idea" of your intake mani getting dirty on the inside...which is ridiculous in itsself.

My car isnt a daily driver its a weekend warrior :laugh:
When its running

I am just cleaning up the engine bay and making room on the firewall for my new afpr.

One question, I assume that that is a checkvalve of somekind right before the hardline that goes back to the tank. I remove the entire thing and gas and fumes came rushing out. I unplugged on the other side of what I think is a check valve and nothing. My question is should I leave that check valve on so that the tank can breathe when it needs to. Also if I do leave it on, will it be putting fumes into my engine bay while driving?

Thanks

A bad side effect to pluggin the fuel tank line is gas vapor builds up in the tank which increased the chance of an explosion on impact.

Well then a good question would be what equipment does your gas tank need to breathe properly? I assume the whole EVAP system needs to be intact to do this. Or is it like Stoner said and you only need the check valve hooked up there with the charcoal canister (to limit the smell) to properly vent the tank when there's enough pressure? Is it a stand-alone check valve that opens at a certain pressure by itsself or is it controlled through something else?

Lots of ppl say this is bad. But your a wiseman Is it good or bad to take out the charcoal canister?

Isn't the gas tank always under pressure?

I plan on blocking all the ports on the evap canister.
