5.9|6.7 Cummins Factory Replacement Oil Feed Line – Fleece FPE-CRTFL-OE

Restore reliable turbo oil supply and protect your investment with this premium factory-style replacement from Fleece Performance Engineering.

The factory hard oil feed lines on 5.9L and 6.7L Cummins engines are notorious for cracking, restricting flow, and contributing to premature turbo failure—especially on high-mileage trucks, tow rigs, and modified builds. The Fleece FPE-CRTFL-OE solves these issues with a direct-fit, high-performance upgrade that delivers consistent oil volume and pressure to your turbocharger.

Why Upgrade to the Fleece Oil Feed Line?

This is not just a replacement — it’s a meaningful upgrade over the brittle factory metal tubing. Built with extra-flexible -6AN smooth-bore Teflon (PTFE) hose protected by a high-temperature sleeve, it offers superior resistance to heat, vibration, abrasion, and corrosion while providing unrestricted oil flow to the turbo bearings.

The kit includes two precision-machined aluminum -6AN to M12 fittings with sealing washers for a clean, leak-free connection at both the engine block and turbocharger using the factory oil feed ports.
