Servicing vapor canister?

Servicing vapor canister?
Well, I have to replace the absolutely nasty hoses to my charcoal canister, and I noticed that the hold-down for it is so rusty that it's mostly crumbled away. However, the unit doesn't seem to want to come loose, and I'd like to check the canister filter if it has one, and make sure the purge valve works properly, and replace that nasty water-holding rusted bracketry. How does this thing unbolt?

There's a screw on the side that holds the canister tight, then two bolts through the bottom of the bracket to connect it to the core support. This one is missing one of the bracket to core support bolts, you can see the hole across from the bolt that's there. I've never worked on the canisters, so I can't help you with that part of your project. John

Those holders do tend to self destruct from moisture sitting between it the the canister.
Great pics and explanation by John, the assembly manual should show how it bolts in and the service manual shows how to service it too. If you don't have them register at the really cool Wildaboutcarsonline site and in the downloads section you can look at both of them in PDF form.
They have all kinds of cool stuff.

For years I was just throwing these puppys away. "I don't need no stinkin smog stuff on my car" But now that many of us are trying to make things original these are getting hard to find. This ones not perfect, it does have pitting. But I believe the metal is solid and with a heavy primer before painting black it might look OK. If you'd like, I could pull it off the core support and send you more pictures. John

I'm one of those guys who just wants to have his car look good and be as rugged as possible for years of trouble free driving, and that includes passing emission inspections in states that aren't as leanient as Texas in case work takes me elsewhere.
From what I've heard, vapor canister isn't really much of a big deal either, as opposed to the obnoxious problems you can get from things like EGR.
