Removal of Charcoal Canisters (fuel tank vents) okay?

[tom91ita]

i pulled mine years ago to get rid of that pollution crap but now when looking at the rules, it seems that there is not as much "emissions" related as i seemed to recall.

is this proper or do i need to find some parts?

What do the canisters do? I've never heard of these before.

[Knestis]

Mine came out as part of the fuel tank/pump/lines system that got replaced by a fuel cell. I'm not sure what clause one would use to take it out if the stock tank were retained, but I've never thought about it really...

hydrocarbon emissions vent from the fuel tank.

when the car is not running, any fumes vent through the activated carbon. the carbon captures the fuel vapor.

when you run the car again, it sucks air through the carbon and strips the hydrocarbons back and effectively regenerates it for the next time.

Isn't it essentially an emissions device?

I had one, and removed it.....

It is, but Tom's got a point...read the regs...

somehow, I don't think anyone's going to lose sleep if you remove your wash...er, charcoal canister.

[tom91ita]

it is an emission device but i have not seeing the rule that allows its removal.

or is it a general issue in the GCR and not in the IT rules?

[TomL]

It's always interesting when you go back and reread the rules you thought you knew. I think Tom is right. The only emission controls that are listed for removal are air pumps, EGR (and associated lines) and the catalytic convertor. Maybe Kirk's fuel cell rationale could be applied, but that seems a stretch.

And I don't think there is any general language allowing emission control removal, since the amount of such removals that are allowed vary by category.

Where's the smiley for letting sleeping dogs lie?

OMG Tom!! You've done it! We should now be able to officially remove the washer bottles because you've come up with a new item to supercede it.

I promise to never look at your car wondering where the charcoal canister is. lol

[Andy Bettencourt]

Yup, nothing is in there that allows the removal of any 'fuel tank/system' emmisions. Basically, any emmission device attached to your exhaust system is all you can touch IIRC.

I 100% agree that if you put in a fuel cell, you can remove that and it's compnents and replaced with the cell and what it needs to function.

Yay! I'm not a dipshit this time...!

the roll cage rules for IT are now part of this right?

ROLL CAGES FOR GT AND PRODUCTION BASED CARS

So my IT car is a "Production" based car, right?

So then I can remove the canister per this right?

Factory installed gas tank evaporative emission control devices must be removed from all Production and GT Category cars.

[Ed Funk]

Opinions may vary...

[Greg Amy]

Good try, but...nope.

When referring to the rollcages, it's actually read as "production based cars" (or, more accurately, "production-based"; note lower case, referring to a description of the vehicle); when referring to the evap systems it's "Production" (note capitalized pronoun, referring to a specific category).

It *was* a good try, though.

But, if it's legal to remove evap system with a fuel cell, and given IT is not required to conform to GCR fuel cell specs, then you can declare your stock tank a "fuel cell" and do whatever you want with it...

Just remove the damn thing. No one gives a flying flip.

My Cannister (long gone) was connected to the air filter housing for the stock carb. (Its purpose is to capture gas vapors when the car is shut off and cleanse them--not sure if they really work).

Accordingly, it was removed since ITCS D 1 c permits the removal of air cleaner assemblies..and all kinds of oter stuff (including housings, etc) located ahead of the carb. It was in front of the carb, albeit inside the left fender.

"Etc" is a good enough excuse.

YMMV

The context of this thread is fuel tank 'emissions'.

[joeg]

Andy--Charcoal cannisters are also connected to fuel tanks.

[Andy Bettencourt]

And that is the point. There is no provision in the rules to remove them.

2. Those vehicles which have emission control devices removed and which are not registered and licensed for street operation may use any gasoline meeting the require- ments of GCR Section 9.3 Fuel.
