Injector Return Line Fitting Repair for 6.7L Powerstroke Trucks

A broken injector return line fitting can leave your 2011-2016 6.7L Power Stroke stranded with a costly and frustrating fuel leak. The factory plastic fittings are prone to failure from heat, vibration, and frequent disconnections during fuel filter maintenance. If one cracks or breaks, it can cause fuel leaks that affect engine performance and leave you needing an immediate repair. Luckily for you, the Fleece Injector Return Line Repair Fitting offers a permanent solution, replacing the weak plastic fittings with durable billet aluminum. This upgrade ensures a secure, leak-free seal and eliminates the risk of a non-repairable fuel line failure. This kit includes five fittings, making it ideal for fleet owners, diesel mechanics, or anyone who wants to have spares on hand. Whether you're maintaining multiple trucks or simply want to be prepared for a quick repair, having extra fittings ensures you won’t be caught off guard by an unexpected failure. The kit also comes with a service kit that includes replacement O-rings and a locking tab, allowing for easy maintenance if needed.

High-Quality Construction & Straightforward Installation

Durability is another key advantage of these fittings. Made from heavy-duty billet aluminum, they are far stronger than the factory plastic version and can withstand the extreme temperatures and vibrations found in a diesel engine bay. The internal dual O-ring design ensures a tight, secure seal, preventing leaks and maintaining proper fuel system operation. Unlike the stock fittings, these are serviceable, meaning you can replace individual components rather than the entire fitting if needed. Better yet, installation is straightforward and does not require any major modifications. The fittings are designed to work with both OEM and aftermarket under-hood fuel filter assemblies, including those from Fleece Performance. They are also compatible with trucks equipped with an S&S Diesel Motorsport DCR conversion kit or the CP4 Disaster Prevention Kit. Once installed, you can expect reliable fuel system performance without the worry of a fragile plastic fitting failing at the worst possible time.
