Abstract
A control system for a fuel delivery system provides enhanced functionality and diagnostic capabilities relative to known systems. In accordance with one aspect of the invention, enhanced functionality and diagnostic capability is provided by integrating the pump controller and the tank gauge by way of a control or integration unit. The control unit includes a microprocessor and communication hardware for communicating with the tank gauge and the pump controllers. In accordance with alternate embodiments of the invention, a control unit is included which provides additional functionality, such as automatic logging of controller faults.
