D Slater Thank you for these pictures. Half my problem solved.
I'm going through the same installation. Based on your pictures I have all the right parts. What I've been looking for are pictures of the priority valve installed and a plumbing diagram. Is there any chance you have pictures of these?
FYI, I have a the same unit off a 400 and looking to install on a 300 row crop.
Any assistance would be greatly appreciated.
