Abstract: The invention relates generally to a system and method for testing fuel evaporative systems, and more particularly to a stand-alone tank tester system (and method) for testing vehicle fuel tank integrity. Furthermore, a self-contained calibration tank with switchable leak sizes for calibrating the tank tester to multiple leak sizes is provided. Constant flow and vacuum methods for testing fuel tank integrity are also provided.

Abstract: A computer-implemented universal automotive maintenance component controller apparatus that may be used as common core enabling a user to interface with, control, and analyze data from, various modular automotive maintenance or diagnostic equipment and/or components regardless of the type or manufacturer of the component. The universal controller of the invention may include a processor and a control application, the control application including one or more software modules that enable the processor to control one or more connected automotive maintenance components. The universal controller may also include one or more component interfaces operatively connected to the processor, wherein each of the one or more component interfaces is configured for one of the plurality of automotive maintenance components.
