I think the zip ties will hold. I use them on the tire chains of my bobcat. They take a real beating. Slit any plastic tube and slide it on from bottom use that silicone rescue tape from state fair at top and every 6 inch or so to close tube and lock at bottom and top with tape. That will also do brake line if you want. I use fuel hose as standoff with zip tie.
