I’m in the process of turboing my ef. I’ve been looking at that canister with great contempt. I want to get rid of it, but what do I do with all the lines?
How do I hook up the purge cut-off valve? I’m sure I need it right?
What is the red vacuum line running to?
I’m using a map sensor on the throttle body so I don’t need the stock one.
Do I just plug the vacuum port on the throttle body?
Thanks in advance.

 

What motor is it?

Basically, but the what the hell is that...thing...run a longer hose from it down to where the hose on the bottom of the charcoal canister used to lead to. Its your fuel tank vapor vent

 

yeah plug everything and throw the canister away, but keep the red hose vent open its the fuel tank vent.

Just make sure you rerout it, because it will smell like fuel in your car if you don't

The purge solenoid is simply an on/off switch for vacuum. The purge solenoid controls engine vacuum, which operates a "valve" on top of the charcoal canister. When grounded, the purge solenoid is closed/off, and doesn't let any vacuum pass through it, so the "valve" on the top of the charcoal canister stays closed. This "valve" is opened when the purge control solenoid allows engine vacuum to pass through. When this valve on top of the charcoal canister is open the engine is "sucking" all the stored gas fumes out of the charcoal canister. Hence the engine is purging the canister of all the gas fumes.

Also, the gas tank does not always vent fumes to the charcoal canister. There is another valve located by the gas tank called the two-way valve. This valve allows a certain amount of pressure or vacuum to build before it opens.

Reasons for/against a charcoal canister:
If a gas tank was perfectly sealed many problems would occur. Such problems include:
1.) The fact that pressure changes with temp (PV=nRT), so when it get hotter outside, the pressure or volume will have to get more/bigger
2.) As gas is pumped out of the tank a vacuum would occur in the tank.

So now we have established that a gas tank HAS to be vented.

Remember the 1970 clean air act? Cars before 1970 and trucks before 1976(?) didn't have any way to catch these gas fumes. The tank was simply vented to the atmosphere. This vent was generally located near the gas cap, or was the gas cap.

On my CRX, I completely removed the metal pipe that is sticking out of the firewall. This is the small pipe that connects to the red hose. I didn't want to just leave it, because I though it would look stupid. Now if you look underneath the car, by the gas tank you will see a small plastic cover on the drivers side. Remove this cover, and disconnect the hose here after the two-way valve. Now gas fumes will vent back here and not in your under hood. I’ve been driving my CRX like this for more then 1 year and haven’t had any problems.

If you simply plugged the port that the red hose is connected to, how is air going to enter the tank as the engine draws fuel out of the tank?

 

you got me. that i did leave open

Has your gas cap been pressure tested lately? Maybe it leaks.

 

So im guessing you can only do all this **** when you have a map on you're throttle body. Other wise it's not a good idea i would think, idk how you can just plug all those lines and still not have a problem though with idle and ****.
