Has anyone found a suitable replacement for the carbon canister or tried to overhaul one?

A suitable replacement is to buy a new one from a vendor that is selling one. I would not even bother trying to overhaul one. New is the way to go. I bought mine from Pelican parts and it fit with no issues.

Why do you think you need one? |

Strong odor of gas in cabin whenever I put over 1/2 a tank of fuel in the car. I've been advised that the canister and leaking fuel lines are very likely causes of this. I also want to be sure everything is tight before I commence the 944 fuel plastic tank conversion.

You need to check the fuel tank, vent lines, check valve & control valve for sure. The charcoal canister is not the problem. |

That "advice" is a great reason to get advice here.
Most common cause is a cracked tank. Remedy is to remove/repair, and do a bunch of really good maintenance while you're in there.

I had the exact same issue that you have now. Changing the carbon canister made is tad 'better' but it didn't fix it. The cause is typically the two braided fuel lines in the trunk area. I bet these two lines are no good anymore and they need to be replaced. They are probably perishing from the inside out and soaked with fuel. You will have to remove the external metal cover to get to them and then drop the gas tank to change them. I just did the job myself and it completely eliminated the gasoline smell. Definitely worth doing. My tank is plastic and yours might be as well so I don't think it is cracked.

Placebo.
The charcoal canister is a tank that's stores gas fumes from the tank when the car is parked. The fumes are sucked into the engine when running to burn them. The control valve opens & closes the vent lines depending on whether the car is running or not.
Being that the canister is in the wheel well, completely separated from the cabin, the only way for a cracked canister to be the problem is if there is a hole in your wheel well for the fumes to enter. |

Thank you all for the guidance. I'm certain the tank in my '87 924S is metal and I've been gathering the parts for the conversion to a 944 plastic tank. As I don't have adequate space in the garage, and winter is closing in, I'll undertake the conversion in the spring. In the meantime I'm looking to inspect/take care of all the parts I can get to before it gets too cold.
