The dual Racor was the prefab system, I would have built it myself at a lower cost, but I liked the vacuum gauge and lever layout and knew I couldn't have done it as nicely. The unit ships complete as shown in the pictures except for the backing StarBoard used for mounting in the engine room.

I believe I paid around that price as well and sourced it locally in Annapolis, MD.
