I have Ford 3000 with a Ford brand loader 19529. I broke a line in the loader and replaced it and am wodering how to add fluid to the loader. it has its own pump and as far as I can see doesn't connect to the tractor hydaulics. Is it possible that I need to add fluid beyond just the transmission and rear end? Someone told me all I needed to was to add the tractor and the loader would be taken care of. Is this correct?
