Prevent Costly Fuel System Repairs with Fleece Performance

A broken injector return line fitting is the last thing you want to deal with, especially if it leaves you stranded with a fuel leak. The factory plastic fittings on 2017-2024 6.7L Power Stroke trucks are known to be weak, making them prone to cracking from heat, vibration, and repeated disconnections during fuel filter maintenance. The Fleece Injector Return Line Repair Fitting is a direct replacement that eliminates this common failure point. Instead of relying on fragile plastic, this upgraded fitting is made from durable billet aluminum, providing a long-term fix that won't let you down. One of the biggest advantages of this repair fitting is its dual O-ring design. This feature provides a much stronger seal than the factory setup, reducing the risk of leaks and ensuring proper fuel system operation. A serviceable billet aluminum barb fitting adds another layer of reliability, making future maintenance simple without the worry of breaking a delicate plastic component. If you've ever had to deal with a cracked factory return fitting, you know how frustrating and costly it can be. This upgrade gives you peace of mind, knowing your fuel system is protected from unnecessary failures.
