Mackpro 338 Posted February 26, 2013 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.PV729-PI0787.pdf 1 Share this post Link to post Share on other sites
Challenger 102 Posted February 27, 2013 (edited) 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. Edited February 27, 2013 by Challenger 1 Share this post Link to post Share on other sites
Mack 3P 80 Posted February 27, 2013 Be careful with the O-ring on the hose. We use the removal tool in the plant. Share this post Link to post Share on other sites
