Can't find a charcoal filter pn for a carbed car

[VolvoLatAm]

Hello, my 1982 244 with vin yv1244812c1779435
never came with a carbon filter for the hot start valve...but in other countries it did. I would like to put one on but I cannot find the part number.
Here are the diagrams from the greenbooks:

the part I am lookin for has a single inlet marked, part called "CARB BOWL"

I have seen these as well for classic cars:

Fuel Vapor Charcoal Canister

Fuel Gas Vapor Fumes Eliminator Charcoal Canister Universal Aluminum Premium

use a regular fuel injection one?

Pretty sure there are multiple hole adapter cannisters that use vacuum or positive pressure to bring back fumes to the gas tank. Do you see in the diagram that one tube goes in and then the output is to the atmosphere? You would need to understand how to plumb a canister with different input and output ports if for a different intended application.

It looks like it's just being used as a filter on an atmospheric vent. If the EFI car has an inlet which only connects to the charcoal side, you could just leave the rest of the ports open.

I would have to know the mapping of the ports though

The charcoal can collects fumes and directs them into the intake to be burned off during the combustion cycle. There will usually be a couple regular ports feeding in and one larger port with a purge valve that connects to the intake.

I wonder what is the cheapest/effective one I could find with a replaceable core

I don't think you really do, as far as I know it's literally just a big plastic canister full of charcoal. Hook up your vent to one of the inlet ports, leave the big return port (which goes to intake on an EFI car) open to atmosphere, and plug all the others.

Or if you're really concerned you can go to the scrapyard and find a different evap canister with only 2 ports. For example this one off a early 00s subaru.

subaru one looks perfect...I can go through many of them before paying the vaporcannister prices. thanks

I'm not convinced that you need one at all to be honest.

It's supposed to filter the air going into the fuel tank and collect any fumes coming out of the tank. If you don't care about the gas smell you can just get a breather filter and put that on the vent

 

[VolvoLatAm]

My car does not come with one stock. I don’t like the gas smell from the valve opening. It’s right under the driver side when I open the door. You guys didn’t get carbed cars so you have to take my word on it

Ya, the US has never had cars with carburetors, we went right to fuel injection in 1914.

Get one from an efi car, the vacuum diagram is on a sticker under the hood. 1 line from fuel tank, 1 going back, 1 vent line. 3 hoses, pretty simple.

if this is not done correctly, or a gas vent valve is not working...couldn't pressure could be drawn away from the fuel tank making the fuel pump work harder?

 

[2turbotoys]

Only vapors go through the lines. You shouldn't have pressure in the tank, the fuel pump provides the pressure. If the vent line becomes plugged, the tank vapor locks.
You should make sure whatever valves are in the system work properly.

 

[VolvoLatAm]

so there would be no danger at all hooking up the tank vent and this vent to a carbon cannister with a single out?

[hiperfauto]

Carbon or charcoal canisters typically aren't sealed. The bottom is open to atmosphere and has a foam filter so it should fine.

 

[VolvoLatAm]

most of these tanks have 3 ports - tank, purge, and air. The air vents looks to have like a splashguard over them...

Purge is for my other vapor purge valve?
