I just went and played around on mine, with it shut off the motor has no resistance but I can manually force fluid thru the system by hand spinning the motor aft and watching the air bubbles move around. Also the forward line comes from the feed tube of the tank and the aft line goes to the valve block. Hopefully a lines just miss run but you may want to disconnect the line to the valve block and see if you can get fluid movement by hand. Also my leak came from the hydro block under the main boom where both cylinders come together. I made that free floating as you can't tighten the lines in the position they need to be in as the side plate was in the way. Hope this helps
