This ball valve is perfect for manually-actuated Accusump systems. The driver must open the valve when the car is started and close it when the car is turned off, so the valve must be accesible to the driver. It does not have to be mounted directly on the Accusump cylinder. You can mount it anywhere between the cylinder and the oil system.
Works with 1, 2 or 3 quart Accusumps. Includes ball valve and 1/2 NPT male-to-male pipe nipple.
