Coolant Bypass Hose for 5.9L Cummins 12V

If you're running a 12-valve Cummins and have already installed Fleece’s coolant bypass system—or are in the process—this black nylon braided replacement hose is exactly what you’ll want to have on hand. Built specifically for the kit, this high-quality bypass hose isn’t just a visual upgrade—it’s designed to hold up to the heat, pressure, and daily abuse of a hard-working 5.9L. The black nylon braided exterior adds a clean, refined look under the hood while also offering real-world benefits. It's tough, abrasion-resistant, and won’t crack or swell like lower-grade rubber hoses can over time. That durability is key, especially when you're pushing your truck through long tows, high boost conditions, or hot summer hauls. Installation is a direct swap, no guesswork needed. Everything lines up the way it should, so you can get back on the road or back to work without downtime.
