I am in the process of changing the line from the supply tank to the leveling system pump on my 85 300TD (line was "weeping", appears to be the original line). Tank was dirty inside, removed and cleaned out residue. Now, when I refill the tank, can I just attach a hose to the small return line to the tank, start the engine and flush out the old oil in the system? I read somewhere on this forum that they cracked the bleed valve on the controller in the rear to bleed the system. My system works just fine, no leaks (except for the supply line to the pump) so can I flush it as stated above?
Thanks
Jerry
