Shop LinesToGo for your 2003 GMC Sierra truck fuel lines. Our FL588-B2C set of fuel lines are crafted for all C/K2500HD/3500 with extended cabs and a 6.6L engine Stainless Steel Set. They must also have an engine reading the code LB7.

Fuel Cooler Line included

Not Included in Set: Hoses between fuel line and fuel tank 5070-01B and Cooler Connector Lines FL591-A2B or SS591-A2B. These parts are available for purchase 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.

Fit perfectly.

"Fit perfectly."

— Daniel S. (5/5)

"Good quality and fitment"

— Walter (5/5)

Good fit from engine to tank.

"Quick delivery and the parts fit correctly. A design review might locate the quick connection between the brake controller and the fuel rad maybe 4" toward the rad. The diameter of the assembly on the female end does not fit in the existing support. Cannot recall but the bend in one of the lines was just off enough that it would not clip into the bracket in front of brake control. Relatively speaking, I do not expect any issues with the product. Assembled nicely, as it should. The availability of the fittings to the fuel cooler is greatly appreciated."

— Wayne W. (5/5)

GREAT SERVICE. SUPER FAST SHIPPING

"GREAT SERVICE. SUPER FAST SHIPPING AND EXACTLY WHAT I NEEDED."

— Dennis S. (5/5)

Highly recommended

"Perfect fit with better than OEM quality. The 2 piece lines made installation relatively easy, certainly much easier than the 1 piece oem linesets. I would highly recommend this kit."
