Abstract: A method for diagnosing a component failure in a saddle-type fuel tank assembly is provided. The method includes a) updating a maximum amount to a subsequent amount of fuel if the subsequent amount of fuel is greater than the maximum amount, b) updating a minimum amount to the subsequent amount of fuel if the subsequent amount of fuel is less than the minimum amount, c) determining a fuel consumption amount, and d) determining that one or more of a first fuel level sender and a second fuel level sender have failed if the difference between the maximum amount and minimum amount is less than a first threshold, and the fuel consumption amount is greater than a second threshold.
