I may have access to some bulk carbon that is used in filters. It is in power form not pellets. I was wondering if maybe this could be put in a bag like an old sock or something and inserted in the canister to replace the old carbon. What do you guys think?

carbon

You'll need activated carbon/charcoal ... Otherwise it'll be useless ...

I would think you would need pelletized not powder, to allow air/fuel vapor to penetrate thru the charcoal filter medium...

Since you ask, I think you have a 'SWAP' - a Solution Without A Problem...

The carbon just provides a relatively inert place for gasoline vapor to collect until it can be re-aspirated into the intake. A big inert sponge.

So - what problem are you trying to solve?

The carbon just provides a relatively inert place for gasoline vapor to condense so it can drip back into the tank.

So - what problem are you trying to solve?

My understanding is that the carbon, in the filter, has no short life. It collects the vapors(hydrocarbons), recirculates them, re-uses them to be burned in the system, and is somewhat self cleaning. As far as I can see, they should never need replacing.

Other opinions?

Yes. (IMG:style_emoticons/default/biggrin.gif)

The factory called for regular replacement. Looks like they thought it was a wear item ...

The pellets will eventually turn to dust. I don't think any of the 30+ year old canisters has anything left in them ...

Any good aquarium store has activated carbon in little rocks all bagged in plastic mesh for use in filtering systems. I ditched mine recently since I mostly race locally and never really have more than 1/2 tank of gas.

Thanks for the input. I will get a chance to see the stuff tomorrow. It is in a plant that is being shut down. This material will be tossed. I would have to pay shipping to keep it. I agree that pellets would be better than powder. It was the idea of placing it in bags that may make it usable in the canister.

I agree the pellet type would be better. Power would likely not allow a free exchange of vapor to pass.

As I was changing out my steering rack a couple of weeks ago, I removed the canister and took a look inside. All the pellets look good as new! The seal on one side of the canister had come undone a bit, and I was getting gas fumes in the front trunk. I popped the side back on, making sure it sealed all the way around, and presto-chango, no more gas fumes (YAY!)

Note that it doesn't instruct you to replace, just viaually inspect. You need to make sure it wasn't stolen???

Huh? (IMG:style_emoticons/default/confused24.gif)

Maybe you should have another look at the chart ...

- Maintenance schedule, every 10,000 miles, 12. Activated Charcoal Filter: Visually check

- Replace every 50,000 miles


visually check every 10,000 miles, replace every 50,000 miles ...

Yes - emissions.
