How can you tell if it's low pressure or high? I think the packing was wrong says short low, but have already found it to be long, so how can i find the pressure is it by the color or the piston silver high, black low

My piston is silver

I went to CP site and did some research. See below

Silver piston is Hi pressure 0-500 psi
Black piston is Low pressure 0-300 psi[/B]
