This Mack service bulletin shows how to remove the lines and also the tool part # you can order from Mack. I think you can also use a fuel line disconnect tool as well.

Those lines are terrible. Every I-Shift or MDrive that gets replaced gets 2 new lines and all 4 fittings.

If you need to remove them without the tool you can, remove the white lock, slide the green lock back with a small screwdriver and use a small thin ziptie and wrap/tighten it around the small green tabs, then push in pull out/work the line out.

The tool works awesome.

Cutting them off and replacing them works well too. I hate those lines.

Be careful with the O-ring on the hose. We use the removal tool in the plant.
