And, still have hydraulic leaks on winch circuit! I disturbed the only hose that wasn't leaking when fixing the others, now that last hose is weeping under pressure, als found the drip source on the tank, lowest point screwed connection, of course, so have to drain the tank of 40L, going to be fun. Think I will use a gear pump I have and draw as much down as possible before cracking the final fitting. It's been a long path to success is all I can say.
