Poison Can

[Aptyp]

Alright, so e30's came with a carbon cannister, that catches all the fumes and poisons that evaporate out of the crappy quality gasoline.

Is removing it change anything?
And do I just run hose all the way back past that cannister?

Or does anyone run it and not care about it? just wanted to know.

the black cylinder thing, under power steering reservoir, and over fuel filter on many models.

I would keep it because it is part of your evap system.

[Ray McCooney]

Why part ways with it in the first place?

[Aptyp]

Lol, I don't mean to part ways with it, but i don't understand the concept of it being there, taking up space.

I just wish, there's a way to get rid of it, insted of my jumping on a treadmill. LOL

Every one who goes turbo or m50, keep it around?

actually, doesnt it act as an air IN filter? Usually, the tank is under vacuum because of the use of gas at a constant rate. The overflow bottle above the rear wheel well acts as the expulsive breather.
Thus, clean air is always at the front of the vehicle because at the rear, dust has been stired up. The cleaner the air, the longer the canister will last, the cleaner the intake vent to the gas tank.
Its a good thing to have it located up front, but i've heard of people putting it in the trunk.

[Aptyp]

Hm, very good point. That should have been my logic.

why not just have a standard breather filter? Maybe even run off the air filter box?

[DaveSmed]

Not quite. The fuel cap lets air in the tank.

The EVAP canister catches evaporated hydrocarbons in the activated charcoal and stores them until certain conditions are met as determined by the engines ECM where the canister begins to purge the stored hydrocarbons back into the intake tract so they can be burned.

Downside from removal? Slight drop in gas mileage as the evaporated fuel is simply gone forever instead of being recovered, and your car will smell like gas.


Not really worth removing it.
