and capping off the metal lines?

I know the CC stores gas tank fumes when stopped and vents off to the atmosphere.

Alternatively, what If one was to remove the CC and metal lines and plug In a appropiate size silicone hose and have It directed to down and below the Engine Bay?

 

i ran my 240sx like that...didnt hurt the car but maybe made the hole in the ozone bigger.lol

 

i think mine was removed by the previous owner. it looks like half the engine was removed, i know at least the air pump, EGR and all of there components were removed. the only negative side effects i see from that is a car that doesn't smell so good sometimes and rough idle, it will also die in neutral on a cold start. the smell probably has something to do with the gutted cat though

 

Remove it already! My car is fine, you know you want it gone so do it. You saw the gap it creates!

 

Ha ha.

 

Hey man, I'll even give you the caps, I have some extras.

 

You can remove all the lines and cap whatever else is left. Just when you open the gas tank turn the cap slightly and let it depressurize or whatever

 

Hey guys, if you cap these lines how does the fuel tank vent? Dont you risk vapor lock?

 

i have the charcoal canister but a **** load of pressure still builds up in the tank.....i dont know if it affects your mileage tho.....

 

yeah...when i get real low on gas.....if i turn the gas cap real quick, it will shoot out.....
kinda crazy......
nothing bad can happen from this right????

 

at the back of the tank you'll find the line that the charcoal canister was attached to. Just leave that vented to atmosphere. If you're really conserned about vapors then put an extra 1 way valve on it..done. Vapor lock is by over heating the fuel. IE running the HUGE aeromotive fuel pump and not having a way to bump down the voltage at cruise. Fuel goes whipping around the system and each time it gets a little hotter. Eventually, you MIGHT get vapor lock. Actually in the case of the built up pressure in the tank, the higher the pressure, the harder it would be to boil. If it's creating a vac then watch out.

 

HKS Turbo II,

Send me some caps

 

He's just going to send you an envelope full of golf tee's

 

so just remove all the lines going to and from the charcol canister and leave the one right off of the gas tank vented to atmosphere? then cap off where the other one goes? is it that simple?

 

Yep.

 

or you could hook it back up...

 

That was somewhat helpful, but does anyone (dare I say an "expert") know what the consequences of removing it are?

I'm looking at either capping off both lines right at the charcoal canister, or connecting them together and getting rid of the canister.. I don't know what they do though, so I want to find out before I do anything I'll regret.

 

just dont have any sparks near where it is being vent bear. those are gas fumes. woulsnt that be like an invisible fuse to thew gas tank? id route a hose from the line in the tank to the outside of the car just to prevent any unwanted explosions.

what if you just take the casister out and all the hoses up to the one near the fuel filter, and then route a line from that metal hose to where the the fumes would go anyway, just bypassing the charcol filter. youd still clean the area up by removing the canister, and still route the fumes to where theyre susposed to go?

 

sorry for my misspelling, i was talking to someone and typing at the same time

 

my 1st post, and already im ripping on mother nature

lol, i love the companionship all car owners have, making mad power and not thinking of the consequences.

 

DON'T do it!!! you'll just create later problems...

 

That's very descriptive, please elaborate on what problems exactly, and why that'll occur.

What does the stupid thing DO that it's not ok to just connect the two lines together?

 

the charcol canister stores fuel vapors from the tank, and (im not sure when... at idle, or load or cold start) the vapors are sucked into the cumbustion chamber. your idle would probably go down a little, as the extra fuel vapors are cumbustable and loosing them would mean running leaner.. enough people have it off, try it, and see what happens and then put it back on if you dont like the effects..

 

I took mine off. Ok, lets get this strait. there are two lines going in on the top.... Right? everyone with me

I though that one line was for Fuel, and the other line was for the Crankcase Breather (to depressurize the oil chamber) am i right? or am i an idiot?

Please someone correct me if i'm wrong

If you refer to the Fatory Service Manual you will see-

From the fuel tank the vent line goes to a 3 way connector near the gas tank that has as described in the manual

Port A- the positive pressure inlet (vent line from gas tank)
Port B- open side of valve leading to charcoal cannister to store and vent gas tank evaporative emissions
Port C- check valve that vents to the atmosphere if Port B is not venting (charcoal cannister clogged/full).

It can be seen that if the line to the charcoal cannister is capped off the checkvalve will vent evaporative emmisions from the gas tank right at the 3 way check valve back by the gas tank.

I capped the metal line on the firewall for the charcoal cannister- right next to the main fuel inlet/outlet lines.

It will vent to the atmosphere JUST AS THE FACTORY INTENDED in the advent of a clogged/full charcoal cannister.
