Purging of a fuel vapor storage canister of an internal combustion engine is optimized through the provision of fuel vapor storage apparatus. A real time measurement of the fuel vapor content of the canister is enabled by providing the canister with a fuel vapor sensor located in at least one of the purge line and the fresh air port of the canister. The fuel vapor sensor is most preferably an adsorption sensitive resistor which operates on the principle of adsorption according to Vander Walls &ldquo;a&rdquo; constant, and the electrical resistance of the fuel vapor sensor preferably varies with respect to the fuel vapor concentration present.
