Stop Chasing Coolant Leaks And Upgrade It Right

If you own a 2003-2012 Cummins and you're still running the factory heater lines, you're on borrowed time. The stock quick-connect fittings are known for one thing, leaking. Fleece Performance's Heater Feed and Return Hose Kit replaces those weak points with high-temp silicone hose and a stainless steel riser that actually holds up to real-world use. Whether your truck is a daily driver, a tow rig, or just a weekend warrior, this kit gives you one less thing to worry about under the hood. It's a clean, reliable fix that looks good and performs even better. Fleece includes everything you need to get the job done right the first time, including clamps and Permatex thread sealant. If you've ever crawled under your truck to find coolant weeping from a connection, you already know why this upgrade makes sense. It's not just about fixing a problem, it's about preventing the next one.

Built For Daily Duty And Long Haul Durability

The Fleece FPE-CUMM-HCL-KIT-0312 is a direct replacement designed to solve one of the most common failures in 2003-2012 Ram 2500 and 3500 trucks with the 6.7L Cummins. This kit eliminates the factory quick-connect style fittings and replaces them with a stainless steel barbed riser that ensures a stronger, leak-free seal. The included silicone hoses are built to handle high engine bay temperatures without cracking, splitting, or degrading over time. Fleece engineered this kit to fit like OEM, with no custom fabrication or extra parts needed. It directly replaces several Mopar and Gates part numbers, making it easy to cross-reference during install or repairs. Each kit comes with four new hose clamps and a tube of Permatex thread sealant to ensure a secure and lasting fit. Whether you're fixing an existing leak or upgrading as preventative maintenance, this hose kit offers a smart, long-term solution built for the demands of diesel workhorses.
