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.

1. A method for diagnosing a component failure in a saddle-type fuel tank assembly, said assembly comprising a fuel tank that defines a first chamber and a second chamber, a first fuel level sender configured to provide a first signal indicative of a first fuel level in the first chamber, and a seco

1. A method for diagnosing a component failure in a saddle-type fuel tank assembly, said assembly comprising a fuel tank that defines a first chamber and a second chamber, a first fuel level sender configured to provide a first signal indicative of a first fuel level in the first chamber, and a second fuel level sender configured to provide a second signal indicative of a second fuel level in the second chamber, said method comprising: determining an initial amount of fuel in the fuel tank;storing the initial amount of fuel as a maximum amount and a minimum amount;determining a subsequent amount of fuel in the fuel tank after determining the initial amount of fuel;updating the maximum amount to the subsequent amount of fuel if the subsequent amount of fuel is greater than the maximum amount;updating the minimum amount to the subsequent amount of fuel if the subsequent amount of fuel is less than the minimum amount;determining a fuel consumption amount; anddetermining that one or more of the first fuel level sender and the 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. 2. The method of claim 1, wherein the method further comprises determining that the first fuel level sender and the second fuel level sender have not failed if the difference between the maximum amount and the minimum amount is greater than the first threshold. 3. The method of claim 1, wherein the first threshold is distinct from the second threshold. 4. The method of claim 1, wherein the initial amount of fuel and the subsequent amount of fuel are determined based on the first signal and the second signal.
