Does anyone know of a very small charcoal canister that I could fit to a 1/4" gas tank vent line hose to keep the smell out of the garage? Thanks for your suggestions!
I searched Charcoal canister on evil bay and came up with 1,199 ads with pictures of charcoal canisters from all kinds of vehicles and of every conceivable size and shape. Here is a small one from a Toyota Hilux pickup truck that likely would work. Also on evil bay.
I used a Canister from a mid 70's Camaro, I dumped the charcoal in a glass jar big enough to hold it all with some room left over. I solder two pieces of brake line going through the lid, one above the charcoal, one going to the bottom. The longer piece has a small fuel filter attached to the bottom, and is hooked to the tank. The shorter piece is hooked to a hose going to the frame rail. As the tank vents, all vapors have to go through the charcoal to reach atmosphere. When the engine is running, all air must enter and pass through the charcoal pulling all residual fuel vapors back to the tank cleaning the charcoal. It works really well, I no longer have fuel smells in the garage.
Are you sure it’s gasoline. A PVC system took 99% of the smell out of our garage; I also made sure to install a hose from oil filler tube to the inner area of the air cleaner like the factory did on our 1956 engine. The evaporating gasoline needs a good air cleaner as all the carb vents go into it. Your tank vent could need a canister but I’ve never smelled gasoline vapor from mine. Some tank vents are just a tiny hole in the gasoline cap.
The junkyards are full of charcoal cannisters, cheap. I'd select one with no electrical connections and as few hoses as possible. I saw one from a fuel injected Mazda B2200 recently that fit the bill. Had a simple bolt on bracket (which you want, of course) to an inner fender well.
