Abstract
A diagnostic apparatus for a fuel storage device has a gas introducing passage for introducing gas from a fuel storage device into an intake passage of an internal combustion engine and a shutoff valve that shuts the gas introducing passage. The diagnostic apparatus detects an amount of fuel component introduced into the intake passage via the gas introducing passage when the shutoff valve is in at least one of an open state and a closed state on the basis of the detected amount of fuel component and, upon detecting the presence of the fuel component in the introduced gas, the apparatus diagnoses that the fuel storage device has a fault.
