charcoal canister that takes the fumes from your evap line coming from your gas tank and sends it through your throttle body to burn it. Let me guess, you want to remove it to clean up the engine compartment..

You don't need to remove it, It doesn't hurt anything.

its the charcoal canister for the emissions.

its filled with charcoal and connected to the fuel system. its used to filter and trap fuel vapors, so the vehicle causes less pollutants
----------
i think there are only a few 10mm bolts u need to remove then it is free!!! and feel free to throw it away because its useless!!! lol

wanab03ss

iTrader: (20)

its not useless, it will get you better gas mileage and save mother earth,, anyone who gets rid of it is an IDIOT..............



heres mine..

seriously though you can, if you want vent it through the fender or better yet get a smaller version from say an s10 and run it in your fender area so you cant see it. It really does get you better gas mileage and doesnt hurt performance at all

haha yeah! and i bet yur fuel economy is sooooooo much better since u left yours installed! haha

and im sure mother earth wont punish us too bad (other than a hurricane or 2) if we toss this into the circular filing system.

cool mounting spot!

you guys are just full of usefull cracks huh . For the record I know what it is/does, I just wanted some input on getting rid of it. I think that spot would look better with a little tranny cooler. Measure twice...lol

The transmission cooler won't get enough air there.

No point in throwing away your charcoal canister. You might as well throw away your fuel cap. You'll accomplish the same thing. Fuel vapour evaporating from your tank before it gets burnt. Count on a 10% fuel economy drop.

Cool Ill look into relocating the can then, not just getting rid of it.

And the tranny cooler is going to be taking the place of the can/intake box with a 650 cfm fan on it. I figure if the engine can suck air to burn from that spot, I can cool my tranny from thier using a fan...right? Its just so darn close to the lines in the radiator, I would seriously need only like 2 feet of line and a couple of fittings. Tempting Tempting.

if elevation isn't a problem, it can be mounted underneath like the vacuum reservoir, but on the other side if there's no room next to the reservoir.

Ive owned both cars with and without the canister, and the ones without are impossible to store indoors, cuz they smell like they have a fuel leak, and get fairly "fumey" while driving.

Im thinking of relocating it myself, the only thing i need to work out is where, as it needs to be right side up when relocated to work properly.

I just recently vented my tube out the fender but before that I bought a venting gas cap and capped it,, never smelled any fumes, the only reason I pulled the vac. cap I had over it is to see if itll run better with less pressure in the tank... if no difference Im recapping it.

I removed my canister and threw it away. That turned out to be a major mistake. Now my whole house smells like gasoline, and my wife bitches about it everyday.

So, if anyone thinks they need to get rid of theirs, I'll take it! I need everything: the tank pickup, the check valve, and the canister.

Vapors come out of the carb too. I also wish I could find a big, high flow version of the charcoal filter that came in the stock air filter, but I can't find such a thing.

[QUOTE=F-Body Demon;3840961]

F-body demon or anyone, The hose that comes off the canister by itself, wraps under the other two hoses and towards the front of the car.... Where does that go? To the cruise? to the vacuum canister?

dprest68

iTrader: (1)

I was wondering that myself. My '88 GTA doesn't have that hose going into the fender, but my '89 GTA does have it. Does anyone know?

xX89RSXx

iTrader: (1)

Thread back from the dead........I am missing that hose also. Even though I have TBI It is set up the same. I can not find the answer.

F-Body Demon

iTrader: (1)

one goes to the gas tank, one goes to the vacuum assembly of lines and the other.....

drum roll please

.....

POINTS AT THE GROUND! Its an open line It seriously just goes down the fender and points towards the road.

BTW: This MAY be unrelated. However, I started experiencing zero fuel tank pressurization and fuel pump failures shortly after the relocation of my canister. I lost two pumps in 6 months. Now these events also correspond with the installation of a bad version of the Walbro 225lph pump and then an Autozone pump. But now the second Autozone pump has held up for another 5,000 miles and about 18 months and is still running to this day, but the tank still will not pressurize.

Anyone have any input on the effects of the fuel vapor canister on the fuel system as a whole?

thunder69n

why is there liquid fuel pouring out the bottom of my vapor canister? And the round thing in the picture on the side of his water pump, is that another check valve peice I should replace? I also apear to have two of these, one built on top of my canister, and one in line line liek his. I have a new solenoid on order. ( thing somthing electrical plugs into on top)

Ended up being that I had lines at the tank reversed

Hi Can i Bypass the canister and put like a fuel filter between the line to the tank and the line to the intake to be burned?

Speed Racer

iTrader: (1)

Don't bypass it. It doesn't hurt anything. It keeps your car from smelling like an old piece of ****. You can get all new parts for not much money if you need it.

the tank needs to vent why not burn the fumes.

Speed Racer

And to answer your question: No. There are very carefully designed pressures and vacuums involved to make this system work. If you just hook full engine vacuum to your tank, you'll have major problems. There's a little valve in the top of the tank that maintains a little bit of pressure in there too. Trust me, you want all that to work right. I've swapped fuel tanks and it's a nightmare if that stuff is not working. Oh, and there's a little valve thing for your tank to "inhale" with attached to a bracket behind where the rear driver side seat is. It's the only part you cannot buy new, so take care of it. Someone on here posted a way to disassemble and fix it if needed.

1992transam

all the smog stuff on my car was already disabled like no cat or o2 sensors when i started the car it did smell like gas but i checked the rubber line there was no vacuum leak so i have no idea on what to do i already took the can out and removed the mounting bracket i dont under stand why there would be no vacuum leak if its all unhooked tho do you have any ideas?

Speed Racer

iTrader: (1)

I think it's a minimal decrease to vacuum, so you might not even notice. And there's a little valve thing close to the canister that controls when it "sucks" on it. I'm not sure when it is activated, so you might have checked when it wasn't doing it. But it might do it whenever the engine is on. dunno

If just your lines are rotted, that's a quick easy cheap fix. So, I'd put it back. You don't want gas vapors anywhere!

Drew

O2 sensors? Plural? No thirdgen came with more than one O2 sensor. If you're fuel injected, you pretty much gotta have the O2 sensor.

The charcoal canister doesn't cost you anything but the real estate it occupies. Can't think of any good reason to delete it. You can do any number of hackjob deletes, ranging from just leaving the tube from the gas tank open, or put a filter on the open tube. At best you're just venting gas vapors and fumes into the air, at worst you're messing with the design of the fuel system.

As a general rule, if you don't understand exactly how the system works, and exactly what you hope to accomplish by modifying or removing it, you're best off to leave it alone.

1992transam

ok thank you Drew, how do i wire a o2 sensor it was completely removed by previous owner and because of that the car starts and idles kinda funky! It seems to crank for way to long before it starts seeing as it fuel injected and i guess i will just replace lines and put the canister back in. Also would the coolant temp sensor cause it to not start great i was told that by a guy who kinda knows the 3rd gens. Also i said o2 sensors because i though there was one before and one after the cat. Thank you also Speed Racer.

The o2 gets wired to a purple wire on the drivers side exhaust manifold.
It effects warm engine operation.

happyhapka

I was thinking can you use the small filter but using a much smaller vacuum hose to compensate, how much it would vacuum out is limited if that makes sense.. reducing the line size to real small. after the filter. they have line reducers.


im not sure if even that makes sense lol.


I know people will blast me don't do this, ya I know. just a thought.
