A dense phase flow product delivery system for an agricultural implement is provided. The system comprises a primary container configured to accommodate dispensed product and that includes a product exit. The system also comprises a pressure supply assembly configured to provide a pressurized fluid to the primary container and a delivery conduit connected to the product exit and configured to permit the dispensed product to pass there through. The system further comprises a purge supply configured to provide a purge fluid to the delivery conduit. The system is configured for a dispensing operation in which the pressurized fluid forces the dispensed product in the primary container to flow through the delivery conduit in a delivery direction. The system is also configured for a purging operation in which the purge fluid forces residual product in the delivery conduit to flow in a direction opposite the delivery direction.
