Capacity should be on the sticker under the hood. Pressures depend upon the ambient temperature and the rpm of the engine. Typical low side 30psi high side 225 psi @ 1500 rpm of engine @ 80ÃÂ° ambient
yes i did find it under the hood 2.12 lb... and thanks for the pressure readings..........take care Bob
