A gas elimination system includes a gas elimination device and a priming system. The gas elimination device includes a vortex chamber that forms a vortex in the fluid flowing into the chamber and a particulate filter that removes particles from the fluid. The particulate filter is located in the vortex chamber such that the vortex is formed in a substantial volume of the chamber before it encounters the particulate filter. When the fluid encounters the particulate filter, the vortex is generally stopped, and additional released gasses rise through the open top of the particulate filter. The device also includes an outlet chamber connected to the vortex chamber, and the particulate filter extends into the outlet chamber. A check valve is located at the outlet of the outlet chamber to shut off flow when the device contains excess gas. The priming system in the form of a pillow block is arranged to force air or fluid upward to dislodge the check valve, should it become stuck in the valve seat.
