[RESOLVED] what is this? (Charcoal canister)

[boostingsx98]

i currently have a 98 gsx. I was doing my intercooler piping and there is this black box located in the front lower driverside with all these hoses and lines connected to it...
Can anybody tell me what this black box does and can i remove it so i have more room for my intercooler piping?

Looks like this? (Please ignore the green circle )

That's your charcoal canister. It can be removed if you don't have emissions testing. Otherwise, it has to stay in for your car to pass.

I believe that Is the charcol box on a 2g you can remove it, since it's part of the emission system it will throw a CEL and u may not pass local emissions testing.

 

[boostingsx98]

ok thanks!

It actually doesn't throw a CEL, and you can pass emissions without it.

Don't forget to re-route the vent lines from the gas tank. Otherwise you'll get a nice whiff of gas fumes, bleh.

i want to take my canister off too but how do you reroute the fuel tank hoses? Btw when it gets hot outside where is the gas tank going to vent the fumes if the canister is removed?

The atmosphere if not rerouted correctly.

I'm doing the same thing and have the same question. Also I believe mine is located in a different spot. I think mines under the battery rack, am I correct on this?

 

[snowborder714]

I have the fuel tank vent line just open to the atmosphere. This is how I had read to do it and it hasn't give me any problems.

Yes, James, you are correct that your canister is under the battery. This should make it a bit easier as you don't have the hard lines to deal with as the later 2g's do.

FYI, late model 1999 DSMs actually don't have this.

All the canister does is takes the fuel that evaporates and is temporarily held there till it is drawn into the intake manifold to be burned. It prevents excessive pressure build up in the gas tank. If you remove the can and you roll your car you could leak fuel... something to think about.

 

[snowborder714]

Did yours not come with a canister Mike? When was your car manufactured?

My brother's '99 GSX was made on 11/1/98 and his had it.

 

[No_Skillz]

Strange... maye it's a FWD thing?

 

[Captainredeyez]

Thanks Brian, I'll make sure I vent the line correctly. I'm doing my EGR block-off and emission removal today.

You removing all emissions? Think you could let me know how that works out?

Might be. I just looked up a '98 GST (8/3/97 production date) and tried to find a part number for a charcoal canister. It came up in CAPS as **NO DATA**.

Can anyone else with a late model GST verify this?

 

[bane3d]

I don't think that it's just a FWD thing. On my 97 GSX, I have the cannister underneath the battery and on that side, I have an automatic transmission cooler that was stock for my car.

okay i have questions about this. Do I route the two lines together or do I run them somewhere else??

 

[Captainredeyez]

I just read another post that said put a small filter in place of the canister.

For yall with 98s, they moved the charcoal canister which was under the battery on previous years and put in under the driver side headlight. When they did this they replaced the hose clamp at the end with a tube that pointed down to vent to atmosphere.

95 - Charcoal canister under the battery and hose clamp at the end
98 - Charcoal canister under the driver side headlight and a tube pointing down

 

[Captainredeyez]

Wait I have a question. Will removing the canister mess with the a/c? I know 1 of the 2 lines on the top of it goes to the a/c right???

 

[slipstream808]

I'll chime in on this one. My '98 Spyder GS-T has no charcoal canister. I got it used, but it was stock and unmodded in all aspects. Don't see why anyone would have removed it so I guess the car just didn't have it.

 

[stephen240]

I bought my 99 gst used as well but I've checked several times and I don't see any lines nor a charcoal canister on either the driver side nor under the battery....

So I'm guessing some 99's didn't have charcoal canister's lucky me!!!!

 

[snowborder714]

The picture in post #2 is from a '99 GSX. The GST should have it in the same spot.

Most likely the previous owner already removed it.

 

[PL69]

I baught my GS-T Spyder bone stock with 32 000miles on it and it had NO canister, but I still removed all the fuel evaporation system anyways....

Some of the emissions stuff on late 2g GST's is in the back above the fuel tank. The charcoal canister is actually inside the fuel tank.
