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.

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.
