Are the two loader hoses hooked to the tank and power beyond?This is a picture of a LB1914 with a loader. The hoses go to this diverter valve. It is similar to my LK2554. You just can make out the knob in this picture but you rotate it when you have a loader installed then it will send the fluid to the loader valve first. This is block I was asking if you could take a picture of.
