yeah!

can I?
should I?
how do I?

ive read just remove it and plug the lines and plug the nipple coming off the throttle body and then get a vented gas cap?

sometimes when i go to put gas in and take the gas cap off I get a big whoshh out of the tank....could that be cause the cannister is not working? or something?

ive always changed the little filter thing on the underneath side of it but could the cannister itself be bad?


anyhow, I do wanna delete it anyways.

 

Good question! I'm very interested in the answer as well.....

Consider me subscribed!

 

same

 

I know for a fact that a lot of people have done this without any negative effects. That being said, It has to do with the fuel system, and various pressures, and fumes etc. etc., and I've heard you could potentially be creating a very hazardous situation. I don't know enough about exactly how it works, just relaying what I've heard.

Personally, I relocated mine. Instead of it sitting ABOVE the sheetmetal in the engine bay in front of the driver side wheel well, it now sits BELOW that very same sheetmetal. All I had to do was lengthen some of the vacuum and electrical wires, and fab up a few angle brackets that I made from lowes. Didn't really take too much. works fine. Looks better!

 

whats up man!

yeah i was about to say,

ive read here that some do it with no problems.

I just want to get rid of that stupid lookin thing....im putting a vaccum cannister is its place.

im just going to plug the fitting end on the throttle body and the one coming from the tank im going to put like a small import filter on the end and be done with it.

and leave the same unvented gas cap on.



guess i'll find out what happens.....

My luck it will blow up!

 

I removed mine and put a vacuum cap over the fitting on the TB. I haven't seen any difference at all, at first, I thought I had a mpg increase, but I realized that when I went back to Shell gas, my mpg went down, it wasn't the canister. BP gas made me think I did a mod worth reporting. All it did was remove some crap from the engine bay, although, without it, emissions would be F-ed up, keep that in mind.

 

i removed mine, you need a vented gas cap to do it properly.

 

I basically done what everyone here has said but I left the line from the tank untouched and open and venting into the fender somewhere, been like that for years with no problems.

 

i originally had mine just venting, then i had strong fuel odors and gas leaking out of the hose...

 

same here ! its been 3 years

 

engine bay looks cleaner but thats it.

you wont gain any hp.

 

I dont understand why everyone has a problem with a little black canister that sits out of the way. Your not going to gain anything by removing it. Its job is to recover fuel vapors instead of just venting them into the atmosphere. Does that really sound so bad?

 

yeah thats sounds terrible!!

i think the thing looks stupid sitting there....i just ran a hose from the fuel line to the fender with a little filter attached to it...should be good to go

 

well id leave it alone, especially since its technically illegal to remove it, its part of the evaporative emissions control, suck it up and leave it alone, its dumb stuff like this that gives third gen owners a bad rep, every retard ******* wants to take things off of the car that they dont understand what it is. If half the clowns on here didnt watch horsepower tv they would probably think their cam shaft is useless and they should remove it to save weight! i know thats harsh, but when day in and day out you see people do dumb things to their cars because they own a couple wrenches so they think they are mechanics, and then they finally bring it to you to fix it after they have messed it up uber good you get to the point of wishing people would just wise up and leave stuff alone.

 

The last thing I want is a car that stinks up the garage with gas fumes because I removed something.

 

Unless you're hood is see through, or the car sits in a showroom with the hood up 24/7, what's the big deal? It's like people taking their AC apart at home and venting all that R12 , or 134 into the atmosphere. Not to knock on car "enthusiasts," but you really should take a class and learn how bad these things are, for you and the environment. And I'm all for cleaning up the engine bay, but not for doing it at the expense of legality or function. It's there because it works, it's not the car's appendix, GM put it there for a reason. That being said, do a little research and I'm sure you'll find your answer

 

I just wanna relocate mine out of sight. It's UGLY!

 

I've seen people do some really trick relocations of the air diverter valve, coolant lines, and vapor canister, there are ways to hide it and still keep it functioning

 

so having an original car is bad? Look I was young once.heck I'm 33 yr old now but I've been into musclecars since 15 or so.I at first want to cut,etc everything I got.Work it up,make it loud etc.Over the years ya learn that stock works good,sure little upgrades are cool,but removing that would do nothing but make your car stink.So i guess when ya pop the hook and say wow this looks pretty but you choke on fuel smell its worth it?Why do that?Maybe relocate would be an option but don't ever cut or do something that you can't bolt back on.Unless its a POS and you don't care at all.Ever watch barrett jackson? Did the cut modified cars pull the money or the stock non-messed with ones?just think.In my opinon its not worth it..but each there own.

 

I'm really disappointed in the all the negative responses. I'm not talking about the factual information, but rather the attitude.
Thirdgen.Org has an ENTIRE forum dedicated to appearance and detailing. How is it that some of you can't understand wanting to make you engine bay look better? If removing the charcoal canister is bad, then explain away, please!!!! ...but questioning the reason for doing so?? Are you guys serious? That's a knife in the back to the entire spirit of hotrodding.
If someone actually thought that removing the cam to save weight was an option, it would be clear that they didn't know what they were doing. Hotrodding is about HELPING to educate and inform as to why you can't do it, but at the same time respect the desire to shave pounds to go faster. To berate the lack of knowledge and condemn the idea of cutting weight is bush league and not worthy of calling yourself a hotrodder.

Maybe leaving the canister IS a bad idea. Maybe. Maybe not. So let's work the problem. Appearance wise, it sure would look better not having it. What are the downfalls? Fumes? Smells? What can be done to prevent the smell? What else can be done to collect fumes? Is it safe? If not, what can be done to MAKE it safe? If we're just a bunch of dumb people with wrenches, but YOU are a professional, then are you too good to share you knowledge?

 

They do sound negative.If I came across negative,sorry, just I don't see why modifying something like that would be worth anything.I just know GM wouldn't have put it on unless it was needed.Now relocating it would work,but where?

 

I have been working on cars and modifying them as my hobby for over ten years now. During that time my thoughts changed about modifying cars. I used to believe emission equipment was a stupid waste of space. Then I grew up and learned how things worked and why they were there. The charcoal canister captures fuel vapors that would be vented into the atmosphere for later use. Before they existed around 20% of hydrocarbon emissions from cars were from venting gas tanks. That cant possibly sound good for the air or your wallet. What does it hurt being there? The answer is nothing. You also could relocate it if you wanted to. The whole idea of a clean looking engine compartment means different things to different people. Do a bunch or holes where things used to be really look good? I dont think so. I have seen some very good looking, nicely detailed engine bays that retain all factory emission equipment.

As for the knife in the back of hotrodding, people who hack their cars apart with no regard to the impact of their actions do more damage to hotrodding then someone who says you have a bad idea.

Criticism of cutting weight is also sometimes valid. What do you think that canister weighs? I would bet a pound maybe. What is a pound going to do? The answer is nothing. If you want so save weight get a fiberglass hood.

 

i would have to side with do what you want with your own car.

its not going to get anyone killed removing the canister.

there are tech articles on here about removing the air pump,so what is the big deal with the charcoal cannister?

you could run a purge solenoid without the charcoal cannister.

i bet 9 out of ten of the evap systems on these car dont work anyway.

if your interested in saving the world you should go chase down every single mustang that is running an OFF-ROAD H PIPE.

tail pipe emissions far exceed evaporitive.

is everyones custom tune up to epa standards?


bottom line ----- my car,my choice.not going to kill anyone.my cannister is in the trash,next to the egr,and the air pump.

 

RED86, the point of my post was not to debate the canister topic, but to hopefully get posts more like the one you just posted. He never said he was going to HACK up his car. The OP asked a valid question, to which he got attitude, not help. Attitude, -and not helping is the knife in the back. Hotrodding by nature is to change and tweak what we have. Not all our ideas are good ones, but that's the great thing about the community we have.

If your going to defend removing yours I will defend keeping mine.

Its not going to help anyone either.

The canister does not draw power to do its job.

you could run a purge solenoid without the charcoal cannister.

There is no point in having a solenoid without a canister.

i bet 9 out of ten of the evap systems on these car dont work anyway.

I doubt its that high.

if your interested in saving the world you should go chase down every single mustang that is running an OFF-ROAD H PIPE.

I dont agree with cat removal either.

tail pipe emissions far exceed evaporitive.

The point is you can limit the evaporative ones with no impact on power production.

is everyones custom tune up to epa standards?

No but there is no other option here.

 

the engine draws a vacuum on the tank to purge vapors and run it through the intake to be burned.

the solenoid is the ecms on/off switch as to when this occurs.

 

defending what?

your free to leave yours, and i dont care.im not bitching telling you its ugly and stock looking,but your bitching about emissions and why it should be left.

who ever owns the car can do what they want with it. it can be left or removed.there is nothing to be gained but apperance and that is preference of the owner.



your just looking for an argument,crack a beer and relax.

 

All i know is on my TA the canister is right by my air filter, so deleteing it would make my custum intake cold air easier.

As far as weight, for some every pound matters and in the front those pounds are the most crutial the closer they are too the front(safely of course). I remember as I stripped my stang down i was taking extra this n that out anywhere i could (especially in my front). My friends mocked me, oh that thing doesnt ever weigh a half pound. Like when i cut out the squares of mental on my fenders behind the plastic piece they used too match the fenders too the 87-up bumpers. My stang has the look of a full interior sbc stock crossmember/frontend still and it weights 2564.

I read more than I post, but I will say I'm tired of all the ressitance some meet for a question about what they wanna do. For example EGR removal maybe it's not the best thing, but that's why we are here too share info. You would not beleive the negativeness about header wrap i ran into anywhere i looked.

I haven't finshied with my TA yet, some of us can afford all the nice afftermarket parts, others put in the work and dink around with our current parts too make what we got do it's thing. Now that is Hot-Rodding.

 

If your venting it to the atmosphere there is no vapor build up to burn.

 

I dont see why making an argument for keeping it bothers you.

 

man you are on something............ the vapors would be in the fuel tank.

you know...... where the fuel is stored.........

 

<<<<<<<<<<< options >>>>>>>>>>

cannister in all stock (if when you open your cap you hear a hiss your system is working.)

cannister in the trash,line capped with vented cap

cannister in the trash,line vented in fender with downdraft style hose,stock cap

cannister in the trash,line to purge solenoid,then to engine.(using a newer gm purge solenoid)stock cap

 

Maybe I should ask if you know how it works. Once you remove the can and and put the hose in the fender or buy a vented cap you are venting the fumes all the time. That eliminates the point of the purge solenoid. There will be no build up of pressure in the tank or stored fumes to purge into the engine.

 

now i know your on somthing.................put the pipe down

if your using the purge solenoid you wouldent have the tank open and venting and you wouldent use a vented cap

" the cannister in the trash,tank vapor line to purge solenoid,then to engine.(using a newer gm purge solenoid)stock cap "

there would be no cannister and nothing open venting.it would be easy to hide just a solenoid.

 

The OP profile seems to be a street//strip motor--
cam somewhat big for street? Mild for race?385 stroked
3400 stall. ( 559//565 cam ) 8.9 compression

Does it make a difference at the track with tha can gone???

IMHO, if it's raced more than street, I would remove it.
OK, but if you get inspections for street, I believe it's mandatory to retain smog eqpt.

Yes you can remove it.
Should you?? I can't give an unbiased answer.
How?? There is atleast 1 way stated.

 

Oh wow I missed something. It does not change the fact that you seem to have a poor understanding of how it works. The fuel systems in our cars were not designed to work like your purge solenoid only idea. They were designed to vent pressure to the canister at around 1 psi. If you set it up to vent tank pressure only during the ecms purge request you are inviting fuel system and possible driveability problems. The newer purge solenoid does not address the need for something to keep tank pressure low. If you look at the late 4th gen cars they have similar equipment to 3rd gen cars integrated into the tank assembly.

Im done arguing about this topic. Everyone has their own opinions.

 

What is really impressive is the fact that out hear in California, we have cars that has all the smog equipment plus A\C pushing over 370rwhp that will smoke most of the cars in this post an up 70% of the cars on TGO. So the question is what are you really trying to gain? A clean engine bay is cleaning it up just like it was brand new and not eliminating anything. Get the point? What you guys are doing is taking advantage of the week emissions testing of your state. If your state was as strict as California you would have a different way of thinking. And thats a fact.

I am very disappointed with the fact that almost everyone is arguing about keeping the canister. When I look at my canister, the line that follows up to my windshield is venting vapors. To me, it is not doing a good job at all,but what do I know. Go ahead and school me on what you think I don't know. I personally would love to remove that canister to put a duel battery set up for the custom sound system that I have and future engine upgrades. I would rather see a duel battery set up than this ugly black canister sitting there. When a vehicle is carbed, what do we do with that canister and how does it help then? I am only asking because I have plans on putting in a carb which I believe leaves the canister unused, unless I am wrong. There is no need to be harsh. Please just share what you know with the rest of us so we can be a happy community and not rip each other apart because someone thinks it should stay and one thinks it should go. Lets get along and place nice, I mean, we are all proud third gen owners.

 

What's other Cali cars got to do with the discussion? I don't think anyone here is under the impression that deleting the charcoal cannister will gain them a couple hundred horses. I'm happy for you that you like to keep your car with as much original equipment in it as possible, but if we all did that it'd be boring. Although a "clean engine bay" can mean cleaning it like it was new, I'd say it's safe to assume that what pops into most people's heads when they hear that is a bay without a crapload of wires and tubing and extra parts that aren't necessarily essential to the operation of the vehicle. My suggestion is if all you've got to offer to the discussion is criticism, do us a favour and save it.

 

LOL.....YEAH!!!!!!!



sorry had to ad that.....

 

To each, their own....

 

EXACTLY what I was going to say.

 

GM should of hidden them, course then folks would of bitched about servicing them, but we know no one ever does so chances are 90% of the folks who want to remove it, don't have one that's working right to begin with.

And removing it for looks, will make little impact.


If you can do it cleanly, not a bad idea to run the vent line to a spot where it can be sucked up by the engine. As the most vapors happen when it sloshing around / driving. [why it can stink up a garage, but leave the door open for 20 or so mins after a drive then close it.] Though don't run it direct to a carb vac port, over fill the tank at the gas station and it will suck raw fuel. One thing the canister did when its works right, only lets the engine suck vapor.


And yes a vented gas cap but be smart, pay $5 more and get the uni fit kind that has a flapper door right in the cap.

Never need to remove the cap again to fill up

 

Wow. I took my air pump and AIR lines off of my '87 IROC. Yep, that means my catalytic converter is gone too. Readin all this mess makes me want to run out and take the canister off too. It's my car and I'll do what I want. Most of the smog equipment mandated by the government (BIG BROTHER) in the 80's wasn't worth a crap when it was new anyway. Pick on someone else.

 

I'm sorry that when people discuss things and don't all agree you feel picked on.

 

Nobody is picking on you. Just pointing what is legal to do & what is not. I'd rather keep a couple of "ugly parts" on my car, than be hit with a several hundred fine of tampering with Federal Emissions parts.

 

Now I always wanted to know, do charcoal canisters ever go bad???

 

Is it possible to run that vent line back into the air intake box/tubing/housing, just before the TB???? Instead of just venting it out through the fender???

Dumb Q's......is there any possibility off "backfire" (venting line to TB) if this was done???
