The present system is directed in one embodiment to a vehicle with a cargo tank or reservoir and a pumping system, comprising a centralized controlled area network (CAN) in operative communication with a programmed computing device, e.g., a programmed logic controller (PLC) that may automate the pumping process output to automatically adjust based on demand and may further enable a pump flow rate that is infinitely adjustable to match output requirements. In other embodiments, the pump speed is no longer dependent upon engine speed or RPM. In other embodiments, the CAN may monitor for vapor at the pump inlet and automatically slow the pump speed until the vapor problem is resolved. Other embodiments may comprise the CAN integrating various vehicle and pumping systems to maximize safety and safety issue annunciations.
