Shop LinesToGo for 2006 GMC Sierra Truck EZ Install Stainless Steel Fuel Lines - C/K Series 2500HD/3500 2WD & 4WD Crew Cab 6.5ft & 8ft Beds w/Fuel Cooler Line w/engine code LBZ or LLY (Eighth VIN Digit 2 or D) for 6.6L Duramax Diesel.

Not Included in Set: Hoses between fuel line and fuel tank 5069-01 and Cooler Connector Lines FL591-A1 or SS591-A1. These parts are available for purchase separately.

Please Note: Original equipment Silverado/ Sierra front fuel line sections can be difficult to install from the engine connections down to the frame rail. These LinesToGo 887 Series come with front flexible stainless steel braided Teflon hoses, making a difficult and time consuming job, a whole lot easier and faster. Routing clips and hardware included.

Installation Note: Remove the plastic clips that secure the front fuel lines from the transmission forward, leaving the metal brackets they are attached to. Install the new front fuel lines into position and connect both ends. Secure the fuel lines to the original metal brackets using the clamps supplied in the kit. Adjust the clamp position and angle so that the fuel lines do not make contact with the vehicle anywhere except for at the clamps.

Location: Engine to Hose Connection off Fuel Tank

Please Note: If you have purchased an aftermarket replacement fuel cooler, the fuel cooler connector lines attached to the fuel cooler may be different than the OEM fuel cooler connector lines. As shown in Illustration A, the aftermarket fuel cooler connector lines are made with a straight sharp edge. When these are plugged into the fuel cooler line, they will cut the O-ring inside the connector causing a leak. If you wish to replace the fuel cooler connector lines before installation of the fuel cooler line, they are available to purchase under part number FL591-A as shown in Illustration B.

We are unable to warranty any of our products that are damaged by aftermarket fuel cooler connector lines.
