I ordered a gauge, some fittings, and replacement hoses for two that showed damage. I also ordered some of the Protec Nylon Hose Sleeve. I think the hose routing is not that great. One short line had significant abrasions on the bottom from rubbing against the machine. And the longer hoses really sag. It seems like I should hang them from the arm, but I'm not sure how to do that without creating abrasion points. Is it best practice to have them tight against the arm? Looser, hanging down?
