Hi everybody. I'm thinking on installing a charcoal canister in my 69. It has a 73 carburetor, but the car gas tank has no provision to connect to the canister. Can I install the canister and plug the canister gas tank connection? Or this can cause trouble (i.e. oversaturated/damaged charcoal?)? My goal is to reduce the gas smell when I park the car, as my garage is attached to the house (also it will help to reduce the amount of evaporated/loss gas to the atmosphere, and probably the most important reason, will make my wife happier). Thanks!

See here for how to retrofit a charcoal can properly and effectively. It's true, your gas tank vent doesn't run up to the engine bay as on '71-up (plus '70 California) models. The fuel tank vent on your '69 dumps out under the car on the left side, more or less above the tailpipe. If you want to vent the tank via the newly-added charcoal can, that can be done, but it's not just a matter of running fuelproof hose from the existing tank vent outlet to the "Tank" port on the can; you'd need a liquid/vapour separator valve to prevent liquid fuel reaching the charcoal can. Might be worth the effort, though, if you're trying to make the car stop stinking up the garage and house. In the meantime, yes, you can just cap the can's "Tank" port without causing any problems.

Keep in mind that a properly functioning charcoal canister/evap system saves gas (money).

A fuel tank that is vented to atmosphere is allowing gas to escape via evaporation. That is what you are smelling.

The canister traps those vapors and then directs them to the engine to be used as fuel.

A properly functioning system can increase fuel mileage somewhat. Judging by your signature, I see you're an economodder and every little bit helps.

Thank you Dan!. And about MPG, what the heck! it has a slant six, so MPG is one of the "bragging" points . But for sure I'm looking forward to reduce the gas smell inside the house each time I drive it

Yeah, evaporated gas does not move your car. The trapped fumes will get directed to the engine to be burned and move the car.

Ok, trying to move forward and buying the stuff...

Dan, I found one thread were you provide numbers for new available compatible parts (canister and valve):

http://slantsix.org/forum/viewtopic.php ... ter#449361

The canister picture in this link appears to be a 2 tube canister, when a carbureted system will need 3. The picture is not that clear, and maybe the websites you refer to used the wrong, or a generic picture. Could you (or anybody that has bought the part) confirm that this part will work?

I also found that Napa have this:
https://www.napaonline.com/en/p/CRB270037?interchange=1
that from the picture appears as a direct replacement of a CP3167, but probably made by a chinese manufacturer. Any comments? (See comment at bottom)

Thanks!

UPDATE (I asked Napa, they don't have this, obsolete part... I guess they need to update their website more frequently...)

That NAPA part is same as the CP3167, no longer available, obsolete from everyone. The AC-Delco 215-153 canister will work fine. You don't need three ports; two are plenty: one input (from carb bowl and fuel tank -- can be combined via a tee fitting) and one output (via the purge valve).

Thank you Dan!. Yes, using a tee makes sense.

I finally installed the canister last week. It works nicely, and it reduced substantially the fuel smell (it did not eliminated it completely). I connected it just to the carb (1973 1920 NOS), as I think most of the gas fumes came from the evaporation of the gas inside the carburetor gas bowl when the engine is hot and turned off, and also I still need to figure out the gasoline-vapor separator installation for the gas tank.

I've seen some gasoline bubbling into the carb throat when shutting of the engine (hot) and removing the air filter, so the smell is coming from there. I guess I need a better insulating carburetor-manifold gasket, as the gas level is fine inside the bowl.

Thanks to all for the comments and for the write-up on how to do the mod.

Happy slanting!
