So I cleaned everything off and the leak seems like it's coming from the spool valve. I pointed an arrow here to where I think the leak is coming from, none of the hoses plugging into it seem to have anything coming off of them.
Hey man, any chance you could tell me the part number or explain things a bit as to what you did? I had another guy tell me to check the control box up top to see if there were leaks in that area, which subsequently would drip down on the valve box. But when I popped that open it was dry/dusty, no sign of moisture. Picture below. Any help would be most appreciated.
