Question Charcoal canister - can it go bad or does it go bad?

Just curious - can a 5.0 charcoal canister go bad over time or will it go bad - and if so, what are the signs of a bad charcoal canister (besides outward signs of visible damages)? If they do go bad, HOW do they go bad, or what causes a failure?

Also, I've read quite a few threads where folks have completely removed the charcoal canister on daily driven Mustangs - how does this impact performance, fuel economy (if applicable), engine functionality and drivability?

Any replies are appreciated.

I think the charcoal canister is just for fuel/gas tank ventilation?

I don't have on, but my garage reeks of fuel.

Yes they can go bad. The ways it can go bad are physical damage or if you over fill your gas tank it can overflow into the canister. It is just for HC's. You dont need it. It will not hurt or help performance with it on or off. It just holds HC's from the gas tank until you run your car then it purges it into the intake manifold to be burnt up by the engine. Its just for emissions.

So, if it is removed, what are all of the associated parts that need to be removed with it? Will the car throw a CEL if it's removed?

I am also assuming by your statement if the tank was "overfilled" and this impacted the charcoal canister, that the canister is now "bad" and should be replaced?

yeah, just ditch that damn thing. Follow the line that goes back to the tank. Right underneath your passengers seat you'll see wher it goes from the hard plastic or whatever to rubber, then to metal. Roughly right under your passengers seat... leave it open right there, and ditch ALL other stuff associated with that damn thing. It won't have any effects on how your car performs. Just another useless piece of plastic they put on the car!

I hooked mine all back up. My cat started puking gas out the filler neck one day from the pressure. Car seems to run better too.

u must be hallucinating from the fuel vapors. the canister does nothing to relieve pressure, u most surely overfilled when getting gas, thats why it puked out of the filler neck.

Ah, the canister does vent pressure in the form of accepting vapors through the vent valve in the top of the tank, but it can only take so much. If the tank has been overheated (BTDT on the road course), it'll send liquid gasoline up the vent line to the canister, and the canister is open to atmosphere through a small vent. It's normally totally capable of taking the vapors and either treating them with the charcoal or venting them to the intake depending on the actuation of the canister purge valve, but if it gets hit with liquid gas, it'll saturate, and stink, and be ruined. BTDT too.

From the '92 PCED...

EEC-IV Evaporative Emission System


Fuel Tank Venting

Fuel vapors trapped in the sealed fuel tank are vented through the orificed vapor valve assembly in the top of the tank. The vapors leave the valve assembly through a single vapor line and continue to the carbon canister (located in the engine compartment or along the frame rail) for storage until they are purged to the engine for burning.


Canister Purging

Purging the carbon canister removes the fuel vapor stored in the carbon canister. With an EEC-IV controlled EVAP system, the flow of vapors from the canister to the engine is controlled by a purge solenoid CANP or vacuum controlled purge valve. Purging occurs when the engine is at operating temperature and off idle.

This must have happened to me.. the canister is still there but if I completely fill my tank, I get an extremely strong fuel odor from it. I think some gas is probably going up the line and getting in there. I mean the smell is so strong it worries me.

Just remember, Ford doesn't put stuff on their vehicles because they like to spend money. It's there for a reason. Keep it.

It's there to prevent HC vapors venting to the atmosphere. Same reason the fuel nozzles at the gas station have the sealing ring.

Those vapors are actually explosive. It's not the gasoline that burns...it's the vapor.

The charcoal canister contains activated charcoal which the vapor is drawn through before being injected in the intake. There is an electrical connector and solenoid inside which can go bad.

Some guys have reported strong fuel smells when deleting it. The issue is finding a nice place to vent the vapor without it pooling up. In the right concentration level and with an ignition source...it can ignite.

Has it happened? Prob not. But i'll leave mine alone.

I took mine off and plugged the line. Sometimes I had gas smell and also when opening my gas cap you would hear the air pressure as I slowly opened it up. So I uncapped the plug from the line that the cannister was on and bought a small breather and put it on and now no smell, gas cap no pressure, everything good.
