Removal Of Carbon Canister

[R3N3]

I would like to know how to remove the carbon canister (with pics if possible). i have done a search, but found out its a legal requirement for these to be installed in Aus, which im guessing is the reason for lack of information on this topic. I Live in NZ and our laws are very relaxed compared to yours, so we arent required by law to have one.

Just rip it all out and make sure all the vacuum lines are plumbed back in.

Can't really go wrong with it.

Make sure you keep the line coming out of the petrol tank venting to atmosphere though.

There is quite a bit you get to remove:

Sorry but what does a carbon canister do? just read that basically stop fuel vapour being released? never herd of one till reading ur post.

im in nz too

Yeah pretty easy to remove i done mine along time ago, the concept of these shitty things is to remove the fumes from your fuel tank then returns them into the intake to be burnt up in the engine. Can't quite remember of the top of my head how many hoses go to it but the ones that go to the engine can be taken off and capped or plugged, the solid steel one that comes from the fuel tank can either be removed or shorten it and put a little breather filter on it. IF you don't cap the ones from the engine properly the engine will run like shit. But yeah they are just a useless waste of space.

looks like you have some hard lines in that pic? how far back did you remove the stuff?

the lines from the plenum look easy, it was the other 2 i have no idea about?

cheers

Im pretty sure they right back to the fuel tank, all i done with my mates R34 GTR was cut it shorter along the chassis rail and put a little filter on it as the fuel tank will still need to breathe unless you put another breather system on it other wise you will probably need a car hoist to remove it properly.

i think it was put there mainly for emissions. i dont believe there are gains for removing it, its just bloody ugly lol

[Nur33]

yeah it was for emissions but yeah your right it is ugly as and it just more shit that gets in the way when your trying to do stuff to your engine and no matter how hard you try you will not make it look pretty lol

[R3N3]

so just to make sure, the lines that go to the plenum, i need to block these off. and the hard lines, dont block these off. why are there 2 hard lines for anyway?

cheers

[Nur33]

Im not 100% sure but there should only one hard line, the fuel tanks needs to breathe otherwise the tank will build up pressure on a hot day and that could be messy, the ones going to the intake were there so the fumes could go back into the engine and be disposed of by being burnt in the combustion chambers, so block them off otherwise the engine will not make vacuum and this could cause it to not run healthy or not run at all

cheers for the help, ill give it a crack tomorrow and see how i get on.

Cheers for the help

Just to explain the hard lines in my picture. Even though there are four hard lines, it is essentially just the one that has been cut into pieces since that is the only way to remove it with everything still in the car.

From the bottom of the carbon canister is a rubber line that goes to a hard line. This hard lines runs behind the engine along the firewall towards the drivers side. It then meets another rubber line and then this goes into a hard line running underneath the car along side the chassis rail to the fuel tank.

So the majority of lines you see in my picture are what run underneath the car and along the firewall.

Like I said, you really can't mess it up. Think of it logically. You fuel tank needs to vent, hence the lines needs to be venting to atmosphere. Your engine can not vent, therefore any lines going to it need to be blocked off.

does anyone know what the chunk near/above the rear diff is ? the breather line that comes from the tank goes to it b4 going down then and along the chassis ??
