i freaking love it when I pull into my shop and my mech goes "wtf have you done now that i don't know about" after he sees a bunch of non-oe silicone braided tube everywhere hah.

ever have to clean these canisters out?

Haha, that's funny.

The canisters, as in the charcoal canister? No, first time I've handled one was removing it.

question for those that have successfully removed the canister:

which is in and which is out ?


my assumption is that the larger black hose close to the blue hose flows out of the canister (assumed this because the blue hose goes to the intake so it must be under suction and i assume that both lines on this part of the canister must be under same pressure.

the other black line that is more remotely mounted goes up to open air... so it is probably an inlet tube that goes to a pre-canister filter.

is this correct ?

I don't recall to be honest. What I did was turn on the car and felt which once was sucking my finger in a bit (very weak vacuum) and that's how I figured it out.

The one connected to the pump is the "in" line from the evap tank. The other line is an open air exit behind the wheel liner.

right, so by 'in' do you mean in-- into the evap or in-- into the canister ?

Take a look at this diagram. Line 15 is an open air exhaust behind the wheel liner. Line 3 connects to the expansion tank and this is a vacuum line from the charcoal filter apparatus. Item 6 on the exp tank is where the vent line from the fuel tank is connected.

To remove the charcoal canister you only need to filter line 3 and line 15 can be left alone or removed. Ultimately removing the wheel liner is your best bet for cleanly completing this project.

Dumb (and illegal) modification for a car that sees street driving. There is no power to be gained, and "weight loss" of the canister assembly is inconsequential.

The only measurable change is that you are now venting more combustibles/pollutants to the atmosphere.

Thanks for the feedback, i have already found the same about #15 and have already removed it... i was just at the point of trying to install the 1-way filter correctly for the stub of #3 that remains.

i documented my progress here:

you do realize that my car is a dedicated track car and that the removal of this device is to facilitate aero work. so this modification is neither dumb or illegal for this purpose... is there a reason you even posted in this thread ?

In that case, I am not speaking to you (as you would see from how I qualified my statement within the frame of street cars). The reason I posted in this thread was because on the previous page, there was uncertainty to the street legality of removing this piece of equipment, as well as there being a number of 'hardcore' street cars in this thread, not to mention street cars populating the majority of this corner of the forum. Settle down, Francis.

It would be sad for some poor uninformed individual to wander into the thread, see a 'mod' that yields no functional benefit in a street setting, then risk getting intimate with the long arm of the law.
