Product Overview

Shop LinesToGo for your 2003 Yukon fuel lines. Our FL149-DX5B set of fuel lines are perfect for any C/K1500 model with a 5.3L (L59) engine and flex fuel only.

Location: Engine to Hose Connection off Fuel Tank

Nylon Lines Between Fuel Lines and Fuel Tank:

Nylon lines between the fuel line and the fuel tank are not included. We do not make the nylon lines for this vehicle. However, you can purchase a nylon repair kit, 3071-01, which will attach to your existing nylon line providing a new connector for the supply and return lines to connect to.

Nylon Line Attached to Vapor Line

The nylon line attached to the new vapor line is not a direct replacement. It is only a section of nylon line that will splice to the original nylon line on the vehicle.

On the opposite end of the original nylon line, there are connectors. These connectors may be damaged during removal. If so, we offer repair kits with new OEM connectors. These will, also, need to be spliced onto the original nylon line.
