A compact fuel tank assembly with a readily accessible shut-off valve, a carbon canister nested in the fuel tank for collecting evaporative emissions from the tank as well as from a float bowl of a carburetor, and an air vent and purge port for drawing stored evaporative emissions from the carbon canister into the carburetor for combustion in an engine. To prevent fuel splash from the tank from entering the canister, a fluid trap in the fuel tank passes fuel vapors and returns liquid fuel splash to the tank. Activated charcoal is retained in the carbon canister in a baffle array for drawing and storing vapors in the activated charcoal, as well as drawing off the stored vapors for combustion within the engine.
