You set a basic air pressure behind the piston in the Accusump at 20 or so psi. As long as the valve is open to the engine, oil is pumped into the Accusump whenever oil pressure exceeds the 20 psi. If you shut off the engine and close the valve when you have say 50 lbs of oil pressure, the oil trapped in the Accusump is at 50 psi. When you open the valve to start the engine the oil squirts back into the engine at 50psi. When the valve is open the oil will flow towards the engine anytime the oil pressure is less than the pressure behind the Accusump's piston. I've had one installed for more than 10 years and consider it not only cheap insurance when running hard, but also a source of instant oil pressure on start up. Scott
