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?

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?

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.

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???

WHAT PART OF "REPLACE EVERY 50OOO MILES" DO YOU NOT UNDERSTAND SON?

thats the first time I have shouted online...dont take me too seriously...

Huh?

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.
