Abstract
Fuel systems and methods for controlling fuel systems in a vehicle with multiple fuel tanks are provided. An exemplary vehicle fuel system includes a first fuel tank including a first pressure sensor, and a second fuel tank. The system may further include a fuel tank isolation valve positioned to selectively decouple the first fuel tank and the second fuel tank. The system may further include an electronic controller configured to identify which of the first fuel tank and second fuel tank includes a fuel system leak by selectively decoupling the first fuel tank and the second fuel tank via the fuel tank isolation valve, responsive to an identification of the fuel system leak.
