Abstract
A method for a fuel system is provided, comprising adjusting a volume of a sealed fuel tank while maintaining spatial compartmentalization of bulk fuel within the sealed fuel tank, and indicating degradation of the sealed fuel tank based on a change in fuel tank pressure. In this way, the fuel tank may be tested for leaks without being unsealed, and without engaging the fuel pump or other elements of the fuel delivery system.
