That's very good to know. I didn't realize that they changed the lines with just that setting. I just thought that it was the larger bags. What is the purpose of the dual lines in the pre-G6 models? It's not filling or draining any faster, and just seems to be one more thing to fail (connectors, lines, fittings, etc.).

At some point, it's still a single line to/from the pump and vent hole on the side, so where does it split/T in the case of the MAX?
