SupraD06 Posted June 12, 2012 Share Posted June 12, 2012 Hiya all, just wondering if anyone can shed some light on the hoses going to the charcoal canister? I want to swap the hoses for some blue hose ive purchased, and just wanted to know a few things. First off are they all filled with fluid? And can i just swap them without having to mess around bleeding air out the system etc Any info would be great. Cheers Quote Link to comment Share on other sites More sharing options...
mplavery Posted June 12, 2012 Share Posted June 12, 2012 No fluid mate, just part of the emission control systems Alot of people just get rid of them as they are useless so I have been told Quote Link to comment Share on other sites More sharing options...
SupraD06 Posted June 12, 2012 Author Share Posted June 12, 2012 Thanks for the quick reply, i had thought about deleting it all together, but im sure i read somewhere that it makes the car smell of petrol alot more. ( Might be totaly wrong ) Quote Link to comment Share on other sites More sharing options...
safcdixon Posted June 12, 2012 Share Posted June 12, 2012 Apparently going by my findiings in the search, setting it on fire seems to be the thing to do Quote Link to comment Share on other sites More sharing options...

Thats another thing i found in the seach, aslong as you vent it under the car then there should be no smell Quote Link to comment Share on other sites More sharing options...

Bossco Posted June 12, 2012 Share Posted June 12, 2012 Bin it. It wont smell of fuel in the car. Quote Link to comment Share on other sites More sharing options...
SupraD06 Posted June 12, 2012 Author Share Posted June 12, 2012 Lol, Ok so the main reaction from most folk is to bin it, but what do you do about capping everything off? Has anyone done a guide for deleting it properly? Quote Link to comment Share on other sites More sharing options...
SilentAgro Posted June 12, 2012 Share Posted June 12, 2012 http://mkiv.com/tmp/no_charcoal_canister/ Its backwards as it is from an American site.. But it should still help Quote Link to comment Share on other sites More sharing options...
Colin-mkiv Posted June 13, 2012 Share Posted June 13, 2012 Hahaha, don't let Hodge see your charcoal canister.....I popped my bonnet at his house and his OCD took him by force......he ripped mine out on the spot!!! I dont get any smells etc in my car, just be sure to bend the remaining metal pipe away under the car and you'll be good to go! Gives you more engine bay to polish.

pedrosixfour Posted June 13, 2012 Share Posted June 13, 2012 As far as I can tell the petrol tank vents excees vapor pressure through the charcoal canister. In order to do the job properly the vent pipe from the tank needs to remain vented to the atmosphere. Blocking it just allows a serious amount of vapour to build up in your fuel tank between refills, not a good idea. The only safe way to do this is to connect a proper motorsport approved vent to the pipe, either in the engine bay or back at the tank. This will stop petrol from escaping the tank should you be unlucky enough to roll the car in an accident. To simply leave the pipe open is asking for trouble if you ask me.

Robzki Posted June 13, 2012 Share Posted June 13, 2012 Can I ask what benefit deleting this part has other than a 0.5kg weight reduction? Quote Link to comment Share on other sites More sharing options...
pedrosixfour Posted June 13, 2012 Share Posted June 13, 2012 Can I ask what benefit deleting this part has other than a 0.5kg weight reduction? A bit more room for other things is probably the main reason it gets the heave-ho Rob. Quote Link to comment Share on other sites More sharing options...

I suspect that there is a rollover valve integrated into the tank or the purge line somewhere. It would be very unusual for it to be in the canister. Problem is the Toyota schematic for the purge system doesn't show a rollover valve at all. Might be worth looking on EPC to check where it is.

I found "check valve (for main fuel tank)" on Toyodiy.com, part# 90917-10079. It's situated directly under the charcoal canister. Might that be it?
