From a little research, it appears tha t it is designed for diesel or gasoline engines and connects to the oil path by replacing the drain plug. It runs before engine starts to pre - lube the engine to prevent metal - on - metal contact before the oil reaches the top of the engine. After shutting the engine off, it runs to help cool the engine and prevent coking. It also doubles as an oil pump for oil changes so you can easily drain the engine of oil.
Pictures are of the actual item you will receive. Condition: literally like new except for some minor damage to a couple of the brackets, a s shown in the last photo. One of them has a small tip snapped off, but is included and could be reattached. Another bracket is slightly bent forward, and would probably need to be reinforced before attaching. TAKE A GOOD LOOK AT THOSE PHOTOS! I only have this one and once it sells , it is gone for good! Please let me know if you have any questions. Thanks, good luck and God bles s!
