Features, Description, Q&A, Specs & Installation
Exact Replacement for Reliable Fuel Delivery. This Fine Lines Fuel Lines; Steel replicates the original routing and sealing of the factory lines on your Sierra, ensuring consistent fuel pressure and preventing leaks. The precision-formed steel tubes are zinc-plated to resist rust, maintaining structural integrity in all driving conditions.
Leak-Proof Connections and Secure Mounting. Flared and swaged fittings mate precisely with factory ports, creating robust seals without adapters. Supplied mounting clips secure the lines along the frame rails, preventing vibration and abrasion that can lead to premature failure.
Installation. This product installs by removing the old fuel lines, fitting the new steel tubes along the factory paths using the provided clips, and tightening the flared fittings to the specified torque with standard hand tools.
Application. This Fine Lines Fuel Lines; Steel fits 2004–2010 Sierra 2500 HD Regular Cab models with an 8-foot long box, excluding cab and chassis variants.
