Hi Terry, High pressure ? ,just be aware that you can crack the casting on the pump due to the hidraulice action of a pressure gun , ,the guns that came with these old cars was a low pressure deal .You most likely know but you need to run the belt a little loose to save the bushes but not to loose otherwise you can run hot due to the fan slipping .Also over greasing can end up with some in the Radiator that would require a solvent or W soda to flush it out , I just did mine using Diesel , Ted
