A method and system integrates the monitoring of system components and detecting errors or potential problems (or both) in components of bulk fuel distribution facilities. Generally, the method and system includes a diagnostic support module for identifying what stand alone software modules, what fuel hardware, and what software interfaces/drivers associated with the fuel hardware are present in a bulk fuel distribution facility. After the diagnostic support module identifies the unique system components of a particular bulk fuel facility that can include software and fuel hardware, the diagnostic support module can perform system checks of the system components to determine if any system components are missing or if errors or potential problems (or any combination thereof) may exist in a particular bulk fuel distribution facility. The system checks performed by the diagnostic support module can include comparing information collected from the system components against a predetermined set of validation rules.
