Quincy 325 ROC 11

[lightning struck]

Just purchased a used Quincy 325 ROC 11 on an 80gal tank. A previous owner disabled the hydraulic unloader, and I'd like to replumb it. Does anyone have a picture of a dual tower 325 that shows the unloader? The Quincy manual I was looking at shows the pilot style setup. I would like just a simple unloader since it has a pressure switch already.

Thanks for any and all help!
