Fits 2001-2016 Chevrolet Silverado and GMC Sierra 2500HD/3500HD (6.6L Duramax).

Ensure your turbocharger receives consistent, unrestricted lubrication with the Fleece Performance Remote Turbo Oil Feed Line Kit. The factory turbo oil supply on 2001-2016 Duramax engines is sourced from the #4 cam journal bearing. This design is inherently risky; if the cam bearing shifts or "slips," it can restrict or completely block oil flow, leading to immediate and costly turbocharger failure. This kit solves the problem by rerouting the oil supply directly from the main oil galley rifle on the engine block.

By drawing oil from the block rifle, you provide the turbocharger with a high-volume supply that is independent of cam bearing position, preventing premature bearing wear and extending the life of your turbo. The kit includes a smooth-bore Teflon hose for maximum flexibility and heat resistance, high-quality AN fittings, and the necessary plugs to seal the original factory feed port.

• Bypasses restrictive factory cam journal oil feed
• Supplies oil directly from the engine block oil rifle
• Smooth bore Teflon hose for durability and flexibility
• 12mm and 16mm feed plugs for the stock oil feed port
• Includes 1/4 NPT 45-degree turbo oil inlet fitting
• High-quality AN fittings for a leak-free seal
• Manufacturer Part Number: FPE-DTFL-S3S4-0116

Fits select 2001-2016 Chevrolet Silverado and GMC Sierra 2500 HD/3500 (6.6L Duramax).

Protect your turbocharger and ensure reliable lubrication with the Fleece Performance Remote Turbo Oil Feed Line Kit (MPN: FPE-DTFL-0116). The factory turbo oil feed on 2001-2016 Duramax engines is supplied via the #4 cam journal bearing. This design is inherently restrictive and carries the risk of complete oil starvation if the bearing slips, leading to catastrophic turbo failure. This kit bypasses that weakness by allowing you to supply the turbocharger directly from the oil galley rifle on the engine block.

The included high-pressure hose features an extra-flexible, smooth-bore Teflon core for maximum flow and durability. Fleece Performance provides all necessary hardware to seal the original feed port and secure the new high-flow line, ensuring a leak-free installation that prevents premature bearing wear.

• Bypasses restrictive factory #4 cam journal oil feed
• Supplies clean, high-pressure oil directly from the engine block
• Extra-flexible smooth bore Teflon hose with high-quality AN fittings
