Yeah, this mod is different than the quick valve. The quick valve shuts off the oil at the valve, so the tube is only used during an oil change to drain the tank. This mod, however, has no such valve at the tank as far as I can tell. The line is full of oil all the time, and the oil change is accomplished by removing the plug at the end of the line. That makes the braided cable a necessity to preserve the integrity of the oil system.
