Unfortunately, the few charcoal canisters I've found are a little pricey. I'm sure you could pull one off of a late model car and install it though. Bacically all you need to do is run your vent line to the canister. Most of the canisters have extra ports that go to the intake manifold and purge valves, but you can block them off. The major benefit is that you can eliminate some of gas fume smell in your garage. The rollover valve is a good idea too. I wouldn't want gas blowing out the vent line. http://www.ebay.com/sch/i.html?_nkw=evap+canister
