Shop LinesToGo for all of your 2001 GMC Sierra cooler fuel lines. The FL590-A2A fuel cooler lines are ideal for any C/K2500/2500HD/3500/3500HD models with a 6.6L engine.

The fuel cooler line is included in all the Duramax Diesel Sets so if you are purchasing a complete set such as FL588-A, FL588-B, FL588-C, FL588-D, FL588-E, and FL588-F, the fuel cooler line will be included with this set and you will not need to purchase it separately.

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 under images - 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.
